RESUMEN

Transverse sinus stenosis (TSS) is an abnormality in the cerebral venous system in which the narrowing of the transverse sinus of the brain leads to obstructed cerebral venous outflow. It is an infrequent, incidental radiological finding. However, it is not uncommon among patients with chronic headaches of unclear cause, particularly those that remain unexplained after initial evaluation or those that are refractory to medical treatment. Its diagnosis frequently eludes the initial workup, and a high degree of suspicion should be maintained since its identification can lead to potentially curative treatment. This report describes the case of a 36-year-old female with a history of chronic headache who was found to have TSS. This paper discusses its etiology, pathophysiology, clinical presentation, radiological findings, and management.

RESUMEN

Absence status epilepticus (ASE) is a rare but treatable condition, and when present in older adults, it can be misinterpreted as encephalopathy or behavioral changes. Our case discusses a 63-year-old patient with myelofibrosis and allogeneic stem cell transplant with late-onset de novo status epilepticus. This case report adds to the rare body of literature discussing de novo ASE whose clinical presentation can be indistinguishable from other encephalopathic or behavioral conditions. Moreover, its occurrence during oncologic treatment warrants clinicians to be on the lookout for similar presentations and encourages future reports of this condition in association with similar therapies. This case report provides value to providers treating patients with similar oncologic therapies and highlights the need for ASE to be further studied as it is a possible rare complication of allogeneic transplantation of stem cells.

RESUMEN

BACKGROUND: Acute acquired comitant esotropia caused by prolonged near work, such as the use of digital devices, has been frequently reported in recent years. However, intracranial examination is necessary even for patients with nonparalytic comitant esotropia. Lhermitte-Duclos disease is a rare tumor that grows in layers in the cerebellum. Among those with this disease, cases of esotropia have been reported due to abduction limitation of the eye, but there have been no reports of comitant esotropia. Here, we report the case of a young woman with acute acquired comitant esotropia who was found to have Lhermitte-Duclos disease. CASE PRESENTATION: A 16-year-old Japanese female patient, whose ethnicity was Asian, was referred to our hospital for acute acquired comitant esotropia. Fundus examination revealed papilledema in both eyes, and magnetic resonance imaging of the head revealed a cerebellar tumor in the right cerebellum with obstructive hydrocephalus. She underwent partial tumor resection, and a histopathological diagnosis of Lhermitte-Duclos disease was obtained. However, comitant esotropia status remained unchanged, and she underwent strabismus surgery. Finally, diplopia disappeared completely. CONCLUSION: Neurological and intracranial imaging examinations are essential when acute acquired comitant esotropia is observed. Acute acquired comitant esotropia by Lhermitte-Duclos disease did not improve with partial tumor resection and required strabismus surgery, but good surgical results were obtained.

RESUMEN

Posterior fossa dermoid cysts are uncommon benign congenital abnormalities. Meningitis is seen as a primary symptom in these situations, more rarely we can find cerebral abscesses. In this case, we describe a 4-year-old Syrian boy who presented with headaches and frequent vomiting as his major complaints. No indication of cerebellar injury was present. He had signs of hydrocephalus like grade III bilateral papilledema but did not develop meningitis. The patient was diagnosed with a complete dermal sinus of the posterior cranial fossa in combination with an infected intradural dermoid cyst and a secondary abscess formation. In Conclusion, the preoperative diagnosis of infected dermoid cysts and dermal sinus tracts lacking signs of infection or meningitis poses challenges, particularly when accompanied by hydrocephalus that can resemble cerebellar tumors. Thorough preoperative assessment is vital for these complex cases.

RESUMEN

The complex iron oxide copper and gold (IOCG) Sin Quyen deposit in northern Vietnam is known as hydrothermal veins and multi-stages of mineralization. Thus, it is complicated to make a probabilistic 3D geometric model using traditional methods and to predict the hidden mineral potential. In this study, computer modeling with nearly 8000 archival data was recorded from 146 boreholes within the study area, and the chemical analysis was done on 40 samples. The 3D block model was constructed using geological structure, optimal parameters, and computational tools approach to the 3D geometric models of surface and ore bodies distribution. The Cu and Ag reserves were estimated based on the 3D geometric models. The total reserve of all ore bodies at the current depth was recorded at 540000 and 25 tons for Cu and Ag, respectively. In the study area, almost all ore bodies were observed as hydrothermal vein types, extending in Northwest-Southeast strikes and dipping around 750 m, closest to the geological observation. The mineralization characteristics of the study area are controlled by left-lateral zipper tectonic activity and faults. Based on tectonic and the 3D geometric model characteristics, the Cu ore bodies are trending continuously to more than 300 m depth at the Southeast of Ngoi Phat stream, while the Northwest shows no signs.

RESUMEN

Genitourinary tuberculosis (GUTB), especially penile tuberculosis (PTB), is a disease often overlooked by urological specialists, especially in Europe, where the pathology is less frequent. In this report, we described a case of penile tuberculosis (PTB) characterized by ulcers on the penis. After the patient was administered three months of anti-tuberculosis treatment (isoniazid 0.3 g/qd, rifampicin 0.6 g/qw, and ethambutol 0.75 g/qd), the ulcer disappeared. The patient was followed up for seven months and showed no recurrence.

RESUMEN

Crossed fused renal ectopia (CFRE) is a rare congenital anomaly in which a kidney is located on the opposite side from where its ureter connects to the bladder, merging into the other kidney. It has been linked to other rare congenital malformations, including the VACTERL association (vertebral anomalies, anal atresia, cardiac anomalies, tracheoesophageal fistula, esophageal atresia, renal anomalies, and limb abnormalities), the MURCS association (müllerian ducts, renal, and cervicothoracic spine anomalies), increased incidence of infections, obstruction, cystic dysplasia, and urolithiasis. Although the literature has documented only a small number of cases wherein CFRE coincides with neoplasia, we present the case of a 59-year-old patient with a right ectopic kidney fused to the left one and simultaneous primary renal cell carcinoma. We aim to report and discuss this case and the treatment approach, comparing it with existing literature to enhance our understanding and management of similar occurrences, as partial nephrectomy is uncommon due to the challenging anatomy of these cases.

RESUMEN

A 37-year-old woman was admitted to our hospital due to a loss of consciousness. She had been taking 2 mg of tizanidine for two months to manage shoulder muscle pain at night. On admission, an electrocardiogram showed sinus bradycardia with a heart rate of 30 bpm and QT prolongation (QTc 495 msec). She had a temporary pacemaker inserted in the catheterization room, after which an improvement in her level of consciousness was observed. There were no apparent endocrine disorders or structural heart diseases. The administration was discontinued after admission, and 12 hours after admission, her heart rate normalized to a sinus rhythm of 70-100 bpm, and QTc improved to 431 msec. Therefore, she was diagnosed with tizanidine-induced bradycardia. Although reports of tizanidine-induced bradycardia are rare, tizanidine's central α2 agonistic effects can cause bradycardia, necessitating caution.

RESUMEN

BACKGROUND: Gastroparesis is a condition that affects the motility of the gastrointestinal (GI) tract, causing a delay in the emptying process and leading to nausea, vomiting, bloating, and upper abdominal pain. Motility treatment along with symptom management can be done using antiemetics or prokinetics. This study highlights the diagnostic and therapeutic challenges of gastroparesis and suggests a potential link between facial trauma and symptom remission, indicating the need for further investigation. CASE PRESENTATION: A 46-year-old Hispanic man with hypertension, type 2 diabetes (T2D), and hyperlipidemia on amlodipine 10 mg, lisinopril 5 mg, empagliflozin 25 mg, and insulin glargine presented with a diabetic foot ulcer with probable osteomyelitis. During hospitalization, the patient developed severe nausea and vomiting. The gastroenterology team advised continuing antiemetic medicine and trying very small sips of clear liquids. However, the patient didn't improve. Therefore, the gastroenterology team was contacted again. They advised having stomach emptying tests to rule out gastroparesis as the source of emesis. In addition, they recommended continuing metoclopramide, and starting erythromycin due to inadequate improvement. Studies found a 748-min stomach emptying time. Normal is 45-90 min. An uneventful upper GI scope was done. Severe gastroparesis was verified, and the gastroenterology team advised a percutaneous jejunostomy or gastric pacemaker for gastroparesis. Unfortunately, the patient suffered a mechanical fall resulting in facial trauma. After the fall, the patient's nausea eased, and emesis stopped. He passed an oral liquids trial after discontinuation of erythromycin and metoclopramide. CONCLUSION: This case exemplifies the difficulties in diagnosing and treating gastroparesis. An interesting correlation between parasympathetic surges and recovery in gastroparesis may be suggested by the surprising remission of symptoms following face injuries.

RESUMEN

INTRODUCTION: Lipoma is the most common benign tumor of adipose tissue. Giant lipoma of the breast is defined as lesions larger than 10 cm and weighing more than 1000 g. A breast lipoma rapidly enlarging and fast growing; can be managed as a malignant tumor. It is crucial to make a correct diagnosis to prevent an overtreatment. CASE PRESENTATION: A 48-year-old patient presented with a painless, huge rapidly growing tumor in her right breast. Physical examination and imaging studies was suggestive of benign lipomatous breast tumor: A breast lipoma, a fibroadenolipoma or adenolipoma, an angiolipoma, or a breast fatty hamartoma. The patient underwent surgical excision of the mass, and histological examination confirmed the diagnosis of a giant breast lipoma. DISCUSSION: Giant breast lipoma is a rare benign tumor that develops in the breast tissue. They can mimic various breast conditions, even neoplastic conditions. Giant breast lipomas are often treated with surgical excision to avoid recurrence. CONCLUSION: Giant breast lipoma rapidly growing can pose a diagnostic challenge due to its resemblance to various benign or malignant pathologies. Unnecessary invasive investigations can be avoided with better understanding and improved imaging-based diagnosis of giant breast lipoma.

RESUMEN

OBJECTIVES: Lung cancer is the leading cause of cancer-related death and poses significant challenges in diagnosis and management. Although muscle metastases are exceedingly rare and typically not the initial clinical manifestation of neoplastic processes, their recognition is crucial for optimal patient care. CASE PRESENTATION: We present a case report in which we identify the unique scenario of a 60-year-old man with shoulder pain and a deltoid muscle mass, initially suggestive of an undifferentiated pleomorphic sarcoma. However, further investigations, including radiological findings and muscle biopsy, revealed an unexpected primary lung adenocarcinoma. We performed a systematic literature search to identify the incidence of SMM and reflect on how to improve and build on better diagnosis for entities as atypical as this. This atypical presentation highlights the importance of recognizing and addressing cognitive biases in clinical decision-making, as acknowledging the possibility of uncommon presentations is vital. By embracing a comprehensive approach that combines imaging studies with histopathological confirmation, healthcare providers can ensure accurate prognoses and appropriate management strategies, ultimately improving patient outcomes. CONCLUSIONS: This case serves as a reminder of the need to remain vigilant, open-minded, and aware of cognitive biases when confronted with uncommon clinical presentations, emphasizing the significance of early recognition and prompt evaluation in achieving optimal patient care.

RESUMEN

Saprochaete capitata is an uncommon yeast species; its impact on non-neutropenic patients appears to be on the rise. We describe a case of S. capitata fungemia in a critically ill end-stage kidney disease (ESKD) patient on peritoneal dialysis. The patient presented with mesenteric ischemia and underwent several laparotomies during hospitalization. His hospital stay was complicated as fungemia developed and spread to multiple sites, which resulted in severe complications and ultimately led to fatal outcomes. S. capitata's diagnostic delay is a concern, but matrix-assisted laser desorption/Ionization time-of-flight (MALDI-TOF) mass spectrometry may help provide accurate identification. Our case highlights the need for prompt diagnosis and tailored antifungal therapy, especially when managing this challenging infection in immunocompromised patients.

RESUMEN

The mRNA vaccines for coronavirus disease-2019 (COVID-19) have been implemented across the globe for both emergent and non-emergent applications. We present a rare case of myocarditis following the second dosage of COVID-19 vaccine. In this case, myocarditis was suspected by troponin and erythrocyte sedimentation rate (ESR) levels prior to echocardiography, which demonstrated mild pericardial effusion, mild tricuspid regurgitation, and mild asymmetric left ventricular hypertrophy. Mild to moderate symptoms of myocardial inflammation persisted throughout the patient's admission, which attributed to the clinical presentation of chest pain and palpitations. As the patient had no relevant history to account for cardiac pathologies prior to vaccination, this case report serves to further investigate the association between mRNA-derived vaccination and subsequent acute myocarditis development.

RESUMEN

This report describes a unique case of vascular Ehlers-Danlos syndrome (vEDS) characterized by multiple spontaneous direct carotid-cavernous sinus fistulas (CCF). The patient initially presented with ocular symptoms and was effectively treated with transarterial coil embolization. Five years later, the patient developed recurrent contralateral CCF that required complex endovascular techniques. Genetic testing identified a novel mutation in the COL3A1 gene, confirming the diagnosis of vEDS. This case report provides a near-term perspective on the identification of structural abnormalities in the COL3A1 protein to ensure the safety of endovascular therapy for patients with vEDS.

RESUMEN

Pneumatosis cystoides intestinalis is a rare and usually benign condition in which multiple thin-walled cysts develop in the submucosa or subserosa of the gastrointestinal tract. While usually asymptomatic, severe cases can result in pneumoperitoneum, which can be managed surgically or medically depending on circumstances. A 35-year-old male patient presented with signs and symptoms of intestinal obstruction. Then the patient was diagnosed with pneumatosis cystoides intestinalis. The patient underwent surgery, and antibiotic treatment, and was discharged improved with no incident. Pneumatosis cystoides intestinalis is a surgical condition that resembles other life-threatening top surgical emergencies and affects clinicians' decisions on diagnosis and treatment plans substantially, mainly in low-income countries. So, surgeons have to consider such kind of conditions and avoid the costs and morbidities associated with unnecessary bowel resection or surgery.

RESUMEN

Introduction: Primary breast Burkitt lymphoma is extremely rare. Commonly endemic Burkitt lymphoma presents with abdominal, jaw, periorbital, or genitourinary mass. Case Presentation: We report a case of a 16-year-old girl with rapidly enlarging left breast swelling associated with evening fevers. This was later confirmed to be stage 1 primary breast Burkitt lymphoma involving the left breast. This represents the first described case of primary breast endemic Burkitt lymphoma in Uganda. She was started on chemotherapy and exhibited an impressive response to the drugs. Conclusion: This case raises awareness of rare sites for endemic Burkitt lymphoma in Uganda. Accurately diagnosing this case was of great importance since it determined the treatment modality (mastectomy or not) which would have an everlasting impact on her life.

RESUMEN

Morgagni hernia is a rare congenital diaphragmatic hernia associated with the minor retro-xiphoid region between the sternal and costal attachments. The bilateral and complicated Morgagni hernia occurred exceptionally rarely, at a rate of 4% and 6.5%. An 81-year-old woman with occasional constipation went to the emergency department for epigastric pain and vomiting 3 days before. She could no longer pass gas that caused abdominal distention. Clinical examination and ultrasound showed partial bowel obstruction, an unspecified cause. She received nil per os, nasogastric decompression. The abdominal and chest computed tomography Scan showed the bilateral diaphragmatic hernia, and the dilated loops of the cecum and ascending colon were 7 cm. She required an emergency operation to resolve the etiology of bowel obstruction. The midline incision was chosen to release the hernia contents and repair the posterior sternal defects with Polypropylene mesh. An abdominal approach can solve a bilateral incarcerated Morgagni hernia.
