RESUMEN

INTRODUCTION AND IMPORTANCE: Primary intracranial neuroendocrine tumors (NETs) are exceedingly rare, often posing diagnostic challenges, particularly in non-secreting variants. These tumors may initially present with nonspecific symptoms, leading to delayed diagnosis and potential neurological complications. CASE REPORT: We present the case of a 33-year-old male admitted with a one-year history of progressively worsening headache accompanied by acute left ptosis and diplopia. Initial examination revealed left eye ptosis and hypotropia, indicative of third and fourth cranial nerve paralysis. Cavoscopy revealed a mild anterior wall bulge of the sphenoid with normal mucosa. MRI imaging unveiled an expansive clival process extending towards the sellar region and left cavernous sinus, completely occupying the sphenoid sinus and exerting mass effect on the pituitary stalk. Hormonal assays were within reference ranges, ruling out a hormonally-active tumor. Endoscopic endonasal surgery for biopsy revealed a low-grade neuroendocrine tumor positive for cytokeratin AE1/AE2, chromogranin A, synaptophysin, and beta-catenin, with a Ki-67-labeling index <2 %. Somatostatin receptor scintigraphy confirmed intense hyper fixation of the tracer in the sphenoidal tumor, supporting its neuroendocrine origin. The patient declined surgical intervention after informed consent, opting for C1 somatostatin analogs prior to radiotherapy. One-year follow-up demonstrated symptom stability with no tumor progression. CLINICAL DISCUSSION: To this day, no consensus among reports concerning the optimal management of these cases. Imaging assessment is crucial to validate the primary nature of the tumor and to exclude any distant localization. Various therapeutic modalities, such as surgery, radiotherapy, and somatostatin analogs, should be considered based on the specific characteristics and extent of the tumor. CONCLUSION: Our case is a clear reminder that neuroendocrine tumors should be considered as a differential diagnosis for skull base neoplasms.

RESUMEN

Introduction: Thyroid tuberculosis (TB) is extremely rare. Infection may first occur in the thyroid gland or may be secondary to TB in other parts of the body. The diagnosis is rarely made clinically because the disease's variable presentation often resembles that of a malignancy or an euthyroid nodular goiter. Case report: We present the case of a 40-year-old woman, who presented multiple thyroid nodules in both lobes. Two of these nodules were classified as EU-TIRADS V (European Thyroid Imaging and Reporting Data System). The ultrasound also found an adenopathy of the inferior part of the jugular lymphatic chain, in favor of malignancy. The histopathological examination after total thyroidectomy showed thyroid TB, associated to a papillary microcarcinoma of the right thyroid lobe, and the final examination of the adenopathy showed similar granulomas with caseous necrosis, and no signs of metastasis. Clinical discussion: Thyroid TB is very rare. Its diagnosis is difficult due to a lack of specific signs and symptoms, which is why the diagnosis is most commonly made on pathological examination after thyroid surgery. It is well known that mycobacterial infection creates an environment of chronic and persistent inflammation, with possible DNA damage. This can create a microenvironment that is highly conductive to carcinogenesis, which could explain the discovery of papillary microcarcinoma in addition to thyroid TB in our patient. Conclusion: This report presents a rare case of malicious growth development of thyroid nodules and thyroid TB. Therefore, physicians must always be vigilant when managing thyroid nodules, as there is always the possibility of malignant lesions associated to an inflammatory or infectious cause.

RESUMEN

Introduction: The dacryocystorhinostomy (DCR) procedure is linked to a high success rate; however, cases of tearing recurrence are not rare and should be managed efficiently. Thus, evaluating cases of DCR failure allows highlighting the factors significantly impacting the results in order to realize better controlled primary surgeries. Material and method: Twenty-eight patients were operated in our Otolaryngology Department for endoscopic revision of DCR failure between January 2019 and June 2022. Their clinical presentation, postoperative evolution, and findings of the primary and revision surgeries were assessed until the actual follow-up. Results: The first surgery was based on an external approach in 17 patients and the bicanalicular silicone tube intubation was kept for a mean of 4.25 months. The recurrence delay varied from 0.5 to 9 months. Revision surgery revealed synechia in 10 patients, a completely closed DCR ostium in 22 patients (78.57%) by mucosal scarring and granulation, and lacrimal sac fibrosis in 16 patients (57.14%). A significant correlation was found between maintenance of the silicone intubation tube greater than or equal to 3 months and lacrimal sac fibrosis (P=0.016<0.05). Conclusion: Thus, better controlled primary surgeries with optimal exposure, wild marsupialisation of the lacrimal sac and no longer systematic bicanalicular intubation which should be dedicated to difficult anatomies and canalicular affections should guarantee better functional results.

RESUMEN

The purpose of the study is to evaluate the correlation between caloric test results and video head impulse test (VHIT) vestibulo-ocular reflex (VOR) gains in unilateral horizontal canal deficits in order to define a possible threshold value above which caloric deficits should be associated with predictable low VHIT VOR gains. Caloric test and VHIT were realised in 105 patients presenting with symptoms of rotational vertigo occurring within the last 2 weeks. The authors defined the cutoff value for a caloric abnormality as more than 15% of canal deficit, which allowed us to divide our patients on groups based on the severity of their caloric asymmetry. Then, the authors performed the VHIT considering abnormal horizontal gain as less than 0.8 with catch-up saccades. The authors evaluated the prevalence of results dissociation between the two tests and the correlation between the caloric asymmetry and the horizontal VHIT VOR gains in each group according to the severity of canal deficit. The correlation was considered statistically significant if P less than 0.05 (Fisher's exact test). The caloric test revealed a significant unilateral deficit in 50 patients (47.6%). The interval of deficit between 21 and 40% included 25 patients, 18 (72%) presenting with normal VHIT VOR gains versus 7. On the other hand, for the 12 patients in the intervals of 81-100% of deficit, the VHIT VOR gain was highly abnormal in all cases. In comparison with the normal caloric test group, a correlation between each interval of caloric deficits and VHIT VOR gains has been assessed. This correlation was significant in the interval of 41-60% (P=0.04 <0,05) and in the interval of 81-99% next to patients with a total deficit of 100% (P=0.006 <0.05 for each). It appears that simultaneous affection of high vestibular frequencies evaluated on VHIT may be more likely and predictable above a minimal threshold of 40% caloric asymmetry, with better discrimination between normal and abnormal VHIT above 80%. Thus, they are two complementary tests to use as a couple rather than a replacement one for the other.

RESUMEN

INTRODUCTION: Retromandibular vein ectasia is a rare lesion that is often misdiagnosed and should be considered in the differential diagnosis of neck masses. An accurate radiological diagnosis can avoid unnecessary invasive procedures. PRESENTATION OF CASE: A 63-year-old patient presented with positional, left parotid swelling, whose ultrasound and magnetic resonance angiography indicated retromandibular vein ectasia. Therefore, no intervention or follow-up was needed for the lesion because it was asymptomatic. DISCUSSION: Retromandibular venous ectasia is an unusual focal dilatation of the retromandibular vein that occurs without thrombosis or obstruction of the proximal veins. They may present as an intermittent swelling of the neck, which is triggered by the Valsalva maneuver. Contrast-enhanced MRI is the preferred imaging modality for diagnosis, interventional planning, and evaluation of post-therapeutic efficacy. Conservative or surgical management depends on clinical symptomatology. CONCLUSION: Retromandibular vein ectasia is a rare and generally misdiagnosed condition. It should be considered in the differential diagnosis of neck masses. Appropriate radiological investigation allows early diagnosis and prevents unnecessary invasive. Management is conservative in the absence of significant symptoms and risks.

RESUMEN

BACKGROUND: Isolated sphenoidal sinusitis is an uncommon cause of headaches in children and adolescents. Recognizing the condition on physical examination alone can be challenging, and delayed diagnosis often occurs. CASE PRESENTATION: A 4-year-old child presented with symptoms of headache, fever, and vomiting. Nasal endoscopy, computed tomography (CT), and magnetic resonance imaging (MRI) were used to confirm the diagnosis of isolated sphenoiditis. The patient was treated with antibiotics and steroids. However, the patient developed meningoencephalitis as a complication of the untreated isolated sphenoiditis. CONCLUSION: Isolated sphenoidal sinusitis can lead to serious complications if left untreated. Adjunctive imaging and prompt treatment are essential to prevent such complications in children and adolescents. This case highlights the importance of considering isolated sphenoiditis in the differential diagnosis of pediatric headaches and the need for early diagnosis and treatment.

RESUMEN

Squamous cell carcinoma (SCC) of the auricle is a rare and aggressive entity of cell carcinomas. It is mostly identified in older males with history of sun exposure. After histopathological confirmation, the initial assessment which consists of clinical and radiological evaluation will determine the therapeutic strategy. We report the case of a neglected SCC of the left pinna with parotid and temporo-mandibular infiltration. After surgical resection, the patient underwent a two staged reconstructive surgery. This was followed later on with radiotherapy and chemotherapy. The evolution was favourable for our patient during an 18 months follow-up. This case report underlines the importance of both curative and reconstructive surgery in successfully treating locally advanced tumors of the temporal bone.

RESUMEN

Introduction: Cystic lymphangiomas are rare dysembrioplasias that occur mostly in children. Although benign, these tumors remain potentially life-threatening, due to the possible compression of the upper airway. The management of cystic lymphangiomas is still somewhat controversial, with surgery generally being the first-line treatment. Patients and methods: 17 patients were included in this retrospective study, all aged less than 18 years old and treated for head and neck cystic lymphangiomas at our department between 2007 and 2017. All these patients had received surgical treatment alone. The relevant data were analyzed with SPSS software. Results: 17 patients were included, with a sex ratio M/F of 1,4, and an average age of 4 years old. Complete resection of the tumor could only be completed in 12 patients. No postoperative complications were observed in our series. All the patients were followed for a minimum of 2 years after treatment. Conclusion: Cystic lymphangiomas are rare tumors of mysterious origins. The main symptom is swelling of the affected area. In our series, the results of the surgery were promising and consistent with results reported in the literature. A follow-up study with a larger population could be interesting, to further examine potential prognostic factors.

RESUMEN

Hearing loss can result from a wide range of pathologies affecting patients of all ages. It may be due to abnormalities of the outer, middle or inner ear. In this article, we present a case of a 50 years old female patient presenting to the ENT and Head & Neck surgery department of 20 August hospital, complaining of bilateral hearing loss, in whom clinical examination found right attical retraction pocket with scales and left normal tympanic membrane. Complementary investigations revealed the association of two distinct conditions, rarely described in literature: otosclerosis, and chronic otitis media with cholesteatoma in right ear and left otosclerosis. The challenge in this case was to determine the therapeutic strategy: start with left otosclerosis? the right cholesteatoma? simultaneously treat otosclerosis and cholesteatoma right?

RESUMEN

Background: The relationship between the location of otosclerotic zones and hearing thresholds has been evaluated in several studies and has generated different conflicting reports. This study was carried out in order to evaluate the relationship between otosclerotic zones extension on CT scan and pure tone audiometry (PTA) thresholds, before and after stapedotomy. Materials and Methods: 108 patients with a positive surgical diagnosis of otosclerosis, operated by the same surgeon, were enrolled in this retrospective study, performed in a tertiary referral hospital between 2015 and 2018. Results: PTA thresholds were significantly poorer in cases of extensive otosclerosis (peri cochlear, peri vestibular, or internal auditory canal hypodensities, p = 0,001). However, for cases with hypodensity extending to the endosteum of cochlea (Type III), we have noted a significant improvement in postoperative PTA thresholds (Mean AC (air conduction) = 32,8 ± 8,16/62,97 ± 12,28 dB), Mean BC (bone conduction) = 18,3 ± 8,56/26,25 ± 15,93 dB). Conclusions: In our study, extensive and multifocal otosclerosis lesions had a statistically significant negative impact on postoperative AC and BC threshold; however, type III lesions tend to be associated with a very good prognosis.

RESUMEN

Introduction: Odontogenic myxoma (OM) is an uncommon benign odontogenic tumor arising from the jaw bone. The diagnosis poses a challenge because its clinical features overlap with those of other benign and malignant neoplasms. Although surgery is usually the choice treatment, there is still some controversy concerning surgical techniques and proper indications. Case report: We present the unusual case of an odontogenic myxoma involving the maxilla, diagnosed in a 31 years old patient presenting to our department for facial swelling through computed imaging and pathological analysis. After careful consideration, the patient was treated with conservative surgery, with a satisfying end result. Discussion: Because of its slow growth, odontogenic myxoma is often asymptomatic. The diagnosis is based on clinical, radiological and histological caracteristics. Complete surgical excision is the treatment of choice, but it can be challenging because of the tumor's indistinct margins. Conclusion: Though there are still no clear guidelines for the management of OM in the head and neck region, the general consensus is that the surgical excision should be complete, and patients treated in a conservative manner should benefit from regular follow-ups.

RESUMEN

INTRODUCTION: Chondrosarcomas of the head and neck are extremely rare, accounting for approximatively 0.1% of all head and neck malignant tumors. Mesenchymal chondrosarcomas are particularly aggressive, with a high propensity for recurrence. CASE REPORT: We report the case of a 25 years old man with no prior medical history, who presented to our facility with an aggressive tumor of the left maxilla. Upon radiologic and histopathological examinations, the tumor was revealed to be a mesenchymal chondrosarcoma. The patient was treated using surgical excision of the tumor, neoadjuvant chemotherapy and adjuvant radiotherapy. CONCLUSION: Due to the high risk of recurrence and the possibility of metastasis occurring long after the initial diagnosis, it is important that patients with mesenchymal chondrosarcomas receive close and regular follow-ups after treatment.

RESUMEN

The aim of this study was to translate and verify the psychometric properties of the CES (Chronic Ear Survey Score) in the Moroccan Arabic dialect as well as the evaluation of the quality of life of patients suffering from suppurative chronic otitis media. A cross-sectional study was carried out between 1st April 2016 and 10 January 2017 in ENT department of the 20 August hospital Casablanca. The data were collected using an anonymous questionnaire administered by the physician. The CES scale used has been translated according to international recommendations. Internal Reliability was evaluated by the Cronbach alpha coefficient and validity was calculated through the Spearman coefficient of correlations. Statistical analysis was done using SPSS 20.0. A total of 107 patients were enrolled in the study with an average age of 35 years (standard deviation = 13 years) with a sex ratio of 0.70. About 35.5% of patients perceived their disease as severe. The mean CES was 48 (standard deviation = 15) indicating a significant decrease in the quality of life of patients suffering from CSOM. Good internal reliability was noted (alpha = 0.72). CES scores increased significantly with perceived severity (p < 0.001). The Arabic version of the CES has good psychometric properties attesting to its reliability and validity. Its use would make it possible to better evaluate the quality of life of patients suffering from chronic otitis media and thus be able to compare and choose the optimal therapeutic methods based on the results of this questionnaire especially before and after surgery.

RESUMEN

The association of Hodgkin's lymphoma and Tuberculosis is a rare entity, resulting in misdiagnose or delay in diagnosis of both diseases, since they share similar signs and symptoms, laboratory tests results and imaging procedures. We report the case of a 63 years old man who consulted for a clinical presentation of pulmonary and cervico-thoracic lymph nodes tuberculosis confirmed at the histopathological examination. The evolution after 5 months of antituberculous treatment was marked by the increase in size of the cervical nodes with a papular skin rash, diffuse abdominal pain and more weight loss. The FDG-PET-scan showed multiple confluent hypermetabolic lymphadenopathies on the whole upper body with cervical skin extension, next to hypermetabolic splenomegaly and focal liver hypermetabolism; next to a bilateral pleural effusion. The histopathological examination of the cervical lymph node specimen concluded to a Hodgkin lymphoma classified as Ann Arbor stage III. The chemotherapy protocol was started, while completing his antituberculous treatment. The patient passed away a few weeks later due to a septic shock. We present this case to supplement the rare literature data concerning the association of Hodgkin's lymphoma and Tuberculosis, defining how they impact the prognosis of one another, in order to comfort the importance of tuberculosis screening in lymphoma patients, especially in endemic areas.

RESUMEN

Lateral neck ectopic thyroid tissue remains a rare entity that can be affected by any lesion involving the gland. The origin of lateral neck ectopic thyroid carcinomas still debated between a metastatic disease secondary to thyroid primary tumor and primary malignancy on the ectopic tissue. Anyway, it should indicate an exploration of the gland. We report the case of a 36 years old female with one year history of hyperthyroidism who was admitted for multinodular grade II goiter with a firm mass in the left level II of the lateral neck. The thyroid scintigraphy demonstrated multiple functioning nodules corresponding to toxic multinodular goiter; in addition to two cold hypofunctional nodules. The cervical ultrasound showed a voluminous multinodular goiter classified as EU TIRADS 5. The surgical procedure exposed a multinodular mass, lateral to the internal jugular vein, with the appearance and structure of the thyroid gland and no connection to it. The thyroid gland was exposed next through a collar incision. Each mass was dissected and removed individually. The histopathology examination of the thyroid gland found papillary carcinoma extracapsular extension. The pathology results of the other mass reported multiple colloid nodules with cystic component, papillary in appearance, with the same cancer proliferation, compatible with ectopic thyroid tissue with papillary carcinoma. No lymph node tissue was found. The patient was sent for complementary RAItherapy. We report a rare case of lateral neck ectopic thyroid papillary carcinoma that supplements and supports the lacking literature data concerning the management of this rare entity.

RESUMEN

OBJECTIVE: Cultural adaptation of the tinnitus handicap inventory questionnaire to the Moroccan dialect version. METHOD: We conducted a prospective study over a 3 years period (January 2017-January 2020) in the Otolaryngology Department of Casablanca University hospital. Translation was produced by a forward-backward procedure with analysis of the psychometric properties of the Moroccan version of the tinnitus handicap inventory. RESULTS: The final Moroccan version of Tinnitus Handicap Inventory (THI) was given to 83 otosclerosis patients suffering from tinnitus. They filled the questionnaire twice before surgery and 1 year after surgery.The item-total correlations are all statistically significant (p < 0.001) and vary between 0.279 (item 15) and 0.817 (item 12).The internal consistency of the Moroccan version of THI, assessed through Cronbach's α, was found to be excellent at 0.953. The interclass correlation showed an excellent reliability for all subscales (0.999-1).THI scores decreased significantly from baseline to 1-year postoperative follow-up on all subscale scores, indicating clinical improvement. CONCLUSION: The Moroccan version of THI has a good reliability comparable with translations in other languages and the original version. It is a valid tool to assess tinnitus improvement after otosclerosis surgery.

RESUMEN

INTRODUCTION: The fungal balls of the paranasal sinuses are usually seen in the maxillary and sphenoid sinuses. Although, the lesion of the concha bullosa, without sinus participation, is very uncommon. We report the case of a fungal ball of concha bullosa in an 88-year-old patient. OBJECTIVE: The objective of our review of literature is to investigate the epidemiological, clinical, paraclinical, and therapeutic characteristics of patients diagnosed with fungus ball in concha bullosa. METHODS: A case of a patient who was diagnosed with concha bullosa of a fungus ball is reported. Demographic data, clinical presentation, imaging, and treatments were recorded. Key images were obtained. A review of the literature was also performed. RESULTS: A total of 12 cases have been reported so far in the literature revealed by different symptoms. The mean age was 38.8 years and the gender ratio was ∼12 (female):1 (male). The endoscopic surgical approach was the most frequently used treatment and provides good outcomes. Neither postoperative complications nor recurrences were noted, however, there is insufficient follow-up data. CONCLUSION: Concha bullosa fungal ball is a rare diagnosis that can be revealed by different symptoms. It should be considered in patients with and unexplained chronic facial pain. A preoperative computed tomography scan is an essential tool in making a diagnosis. Endoscopic surgery is the treatment of choice, with a low morbidity and recurrence rate.

RESUMEN

Pilomatrixoma is a rare benign skin tumor differentiating toward hair matrix cells usually encountered in the head and neck region. It is most frequently appearing in the first and second decades of life. Histopathological examination is essential to make definitive diagnosis. Herein, we present an atypical case of multiple pilomatrixomas. A 69-year-old man with multiple voluminous masses over the scalp. Among the three lesions, one was clinically suspicious for malignancy, it measured 17 cm and was ulcerated in places. Histopathology confirmed the diagnosis of pilomatrixoma. The tumors were removed surgically with free margins. Otolaryngologist should be familiar with this benign tumor when evaluating soft-tissue mass in the head and neck region.

RESUMEN

INTRODUCTION: Lipoblastoma is a rare benign tumor arising from embryonic white fat which occurs in the early childhood. It usually arises on the extremities and considered as a rare cause of a pediatric head and neck masses. The aim of this study is to shed light on lipoblastomas as a differential diagnosis of rapidly growing soft fatty masses of children in neck and head area. PATIENTS AND METHODS: A retrospective review of 3 patients with lipoblastoma, underwent Surgical resection (case 1 and 2) by cervical approach. The third patient with a facial lipoblastoma was not operated due to the high risk of facial paralysis. Review of literature, diagnostic methods and genetics of lipomatous tumors are discussed. RESULTS: Complete surgical excision via a cervical approach demonstrated irregular lobules of immature fat cells separated by a loose, myxoid connective tissue. Histology analysis confirmed the diagnosis of lipoblastoma. DISCUSSION: Lipoblastoma is a rare childhood tumor, even rarer in head and neck area. The pathogenesis is unknown, though it is believed to arise from altered embryogenesis of human white fat and genetic predisposition, as chromosome 8 abnormalities may be implicated in the development of lipoblastoma. The presumptive diagnosis is performed by imaging. The most important differential diagnosis of lipoblastoma is myxoid liposarcoma. The mainstay of treatment is complete non-mutilating resection of the tumor to avoid recurrence. CONCLUSION: Lipoblastoma should be suspected in case of heterogeneous fatty tumor in head and neck area, and included as a differential diagnosis of cervical masses in children younger than 3 years. The mainstay of treatment is complete surgical excision with a good prognosis.
