RESUMEN

Extra-pulmonary tuberculosis (TB) of the musculoskeletal system usually manifests with non-specific clinical features, mimicking a variety of diseases. Diagnosis and treatment of spinal and extra-spinal musculoskeletal TB are often challenging. Imaging has an important role in detecting this disease, aiding diagnosis, identifying complications, and monitoring disease progression. Radiographs and magnetic resonance imaging are the key imaging modalities utilized. Radiologists should aim to be familiar with the spectrum of imaging features of TB affecting spinal and extra-spinal locations in the musculoskeletal system.

RESUMEN

Five cases of tuberculous osteomyelitis of the fronto-zygomatic (F-Z) region presented with a non-healing ulcer or discharging sinus in the eyelid skin in healthy children and an adult. Lack of awareness about peri-ocular manifestations of extra-pulmonary tuberculosis and delayed referral to specialists, along with poor compliance to long-term ATT, could be the reason for its underreporting in India.

RESUMEN

Tuberculous osteomyelitis is infrequent and occurs most often in the femur, the tibia, and the small bonne of hands and feet. Herein, we report a 39-year-old female who presented with chronic pain and motion range reduction of the left knee joint for two years. A knee radiograph revealed a geographic lytic lesion of the epiphyseal and diaphyseal region of the tibia mimicking giant cell tumor (GCT). A minimally invasive biopsy of the lytic lesion was performed, and pathological assessment revealed granulomatous inflammation made of numerous caseating necrotizing epithelioid and giant cells granulomas, diagnostic of tibial plateau tuberculosis. This case underscores the importance of taking tuberculosis into consideration in lesions mimicking GCTs in the tibial plateau, especially in endemic regions.

RESUMEN

Tuberculosis manifesting at extrapulmonary sites is relatively rare. Isolated cases involving small bones of the foot are the rarest of the rare. We herein present the case of a 30-year-old Indian female who presented with pain and a wound with a discharging sinus over her left foot. In the absence of constitutional symptoms of tuberculosis, this case was diagnosed as isolated tuberculous osteomyelitis of the left fifth metatarsal and phalanx with the help of radiography, a cartridge-based nucleic acid amplification test, a line probe assay, a culture of the biopsy specimen, and magnetic resonance imaging. She was initiated on anti-tubercular treatment per national guidelines.

RESUMEN

Introduction: Coinfection of tuberculous osteomyelitis with Streptococcus agalactiae has not been reported in an immunocompetent adult so far. The slow progress of tuberculous osteomyelitis, due to lack of significant elevations in the laboratory values and changes in the radiographic appearance, often leads to confusion with brodie's abscess. These two clinical conditions often lead to delay in diagnosis and progressive bone destruction. The aim of this report was to highlight recognizing the possibility of coinfections in tuberculous osteomyelitis and early treatment targeting both organisms simultaneously. Case Report: We report a case of a 24-year-old male patient from Kerala, India presented with pain and swelling over distal leg for 2 weeks along with mild fever for 1 month. Imaging showed a brodie's abscess over distal tibia. Pus culture isolated S. Agalactiae. Bone biopsy reported as necrotizing granulomatous lesion. Computed tomography thorax was suggestive of necrotic tuberculous mediastinal and hilar lymphadenopathy. Based on histopathology, microbiology, and radiological findings, coinfection of tuberculous osteomyelitis and bacterial infection was confirmed and antitubercular therapy was started, along with antibiotics for S. agalactiae. Conclusion: Tuberculous osteomyelitis mimicking brodie's abscess is very rare. It is important to consider coinfection in osteomyelitis and it is essential to do tuberculosis-polymerase chain reaction and histopathological examination, along with bacterial and fungal culture of pus in subacute osteomyelitis for the early diagnosis and treatment.

RESUMEN

Background: Tuberculous (TB) osteomyelitis is a rare, but challenging infection, that mandates antituberculosis antibiotics, and potentially surgical intervention. Per the Gulhane Askeri Tip Akademisi (GATA) classification system, corrective reconstruction is indicated in severe cases, where the kyphotic deformity is >20° (GATA Class III). Here, we describe a case of BCG vaccine-induced lumbar TB osteomyelitis at the L1-2 level in a patient presenting with mechanical pain and a focal, nonfixed kyphotic deformity of 36.1°. Surgery consisted of percutaneous fixation with pedicle screws without debridement, fusion arthrodesis, or anterior reconstruction. Case Description: A 77-year-old male presented with L1-2 TB osteomyelitis secondary to intravesical BCG application. A 36.1° focal nonfixed kyphotic deformity was evident on standing X-rays that reduced in the supine position. He underwent posterior percutaneous screw fixation with rods extending from the T12 to L3 levels, with resolution of his mechanical pain. Nine months later, the CT demonstrated reconstitution of the vertebral bodies (i.e., volume increase of 6.99 cm3 (21%) and 7.49 cm3 (27%) at L1 and L2, respectively). Standing X-rays after hardware removal demonstrated 32.7° of lumbar lordosis and a reduction of focal kyphosis to 12.9°. Conclusion: Here, we present an exceedingly rare case of BCG vaccine-induced L1-2 spinal tuberculosis with extensive vertebral body destruction and deformity. This was effectively treated with standalone temporary pedicle fixation instead of corpectomy and reconstruction.

RESUMEN

We report a 94-year-old patient with a fractured radius that was being managed conservatively. At 2 months, an abscess was observed overlying the fracture site. An MRI scan was done and samples obtained for microbiological and pathological analyses. The patient was diagnosed with tuberculous osteomyelitis. Surgical debridement of the fracture site was performed, and the bone defect was filled with bone cement impregnated with gentamicin and rifampicin. Anti-tuberculosis therapy was administered for 9 months and the patient made an uneventful recovery. Early diagnosis and correct medical treatment depend on sound evidence of tuberculous osteomyelitis. Surgical debridement is essential if abscesses are present in the bone. Level of Evidence: Level V (Therapeutic).

RESUMEN

We share the case of a 86-year-old male patient, followed up for recent left hip pain. Interrogation revealed a fever, nocturnal shivering, and bone pains. Standard radiographs and computed tomography centered on both shoulders and pelvis showed osteoarthritis of the left hip and multiple lytic lesions in both humeral heads and clavicles, suggestive of chronic infectious, metabolic, or secondary disease. Bone scan with radiobiphosphonates showed intense and diffuse uptake in the clavicles, the two humeral heads, and at the cervical and dorsal spine. Biopsy of the left humeral head confirmed the diagnosis of tuberculous osteomyelitis, showing an aspect of caseo-follicular tuberculosis. Bone scan with radiobiphosphonates can be used in our context to search other localizations falling within the framework of a polystotic form, and also to guide nonrisk biopsy in such group of patients.

RESUMEN

BACKGROUND: Tuberculosis osteomyelitis is rarely seen in the diaphyseal bones. It may be confused with Brodie's abscess due to similar clinical, radiological and laboratory findings. Late diagnosis of the disease causes bone destruction. Tuberculosis osteomyelitis of the bone is a rare condition caused by the Mycobacterium tuberculosis. Its incidence has increased in Western countries in recent years due to HIV infection, increasing elderly population and emerging resistant strains. The slow progress of tuberculous osteomyelitis, due to lack of significant elevations in the laboratory values and changes in the radiographic appearance, often leads to confusion with the subtypes of subacute osteomyelitis, defined as Brodie's abscess. These two low-virulence clinical cases often lead to delays in diagnosis and progressive bone destruction. CASE PRESENTATION: We report a 65-year-old male patient who presented to our clinic with pain, swelling and sensitivity in the left leg. Diagnosed with infection in the tibia, the patient had undergone antibiotherapy. However, the patient's symptoms were not resolved and we performed bone curettage and cementation. M. tuberculosis-specific DNA was detected by real-time polymerase chain reaction and the M. tuberculosis complex was produced from the perioperative samples. CONCLUSION: In conclusion, histopathological examination and polymerase chain reaction are essential before surgery of subacute and chronic osteomyelitis with atypical clinical, laboratory and radiological findings for early diagnosis and accurate treatment.

RESUMEN

Tuberculosis in the foot progresses gradually; thus, diagnosis is usually delayed, and early treatment is rarely provided. If osteomyelitis occurs due to delayed diagnosis and treatment, surgical treatment should be considered. We report the case of a 46-year-old man with osteomyelitis of the calcaneus who was diagnosed with multidrug-resistant pulmonary tuberculosis and he was treated with anti-tuberculosis drugs. Bilateral adrenal masses, abscess of both testes and a small wound in the left plantar heel were observed. Both adrenal masses and abscess were regarded as paradoxical reaction of anti-tuberculosis treatment. After 1 month, he developed a pain in the left plantar heel that was compatible with calcaneal osteomyelitis in radiological features. He underwent right orchiectomy for right scrotal abscess aggravation and surgical treatment for left calcaneal osteomyelitis. Mycobacterium tuberculosis was confirmed by polymerase chain reaction. The patient was immobilized by cast for 8 weeks and the heel pain gradually improved.

RESUMEN

A 66-year-old Caucasian female presented with insidious sciatic pain leading to an uncommon diagnosis of tuberculous osteomyelitis with unknown portal entry. The patient did not report a history of a previous tuberculosis (TB) infection and her chest X-ray was negative for TB. Considering TB in the differential diagnosis of a 'bone abscess', it is of paramount importance to come to a correct diagnosis. Conventional radiographs still remain the first-line imaging modality for evaluation of skeletal symptomatology. However, biopsies or aspirates are often needed to yield the definitive diagnosis. The lack of awareness of the potential extrapulmonary involvement of TB leads to an important delay in diagnosis and treatment. Antituberculous drugs should be started at the time of biopsy and continued during 12-18 months, due to poor drug penetration into osseous and fibrous tissues.

RESUMEN

Retrograde intubation is an invaluable technique which can be helpful in anticipated difficult airway situation. In this advanced era where fiberoptic intubation and video laryngoscopes are in abundant use, retrograde intubation is a forgotten technique. However, it may be useful in various difficult airway situations in this advanced era. In our case the patient had a bitter experience with previous fiberoptic intubation. Owing to that we had planned and performed a fiber optic guided retrograde intubation, where we had kept the fiberoptic bronchoscope in the pharynx keeping larynx and vocal cords in the focus to facilitate the emergence of guide wire through one of the nostrils as well as direct visual confirmation of intubation. This fiber optic guided retrograde intubation is a first reported case of its kind in a predicted difficult airway which can be beneficial in different difficult airway situations.

RESUMEN

INTRODUCTION: Skeletal tuberculosis involving the small bones is less common than pulmonary tuberculosis. Tuberculous dactylitis involves the short tubular bones of the hands and feet more commonly in children. The bones of the hands are the one's more frequently affected than bones of the feet, with the proximal phalanx of the index and middle fingers as the commonest sites for infection. Spread to the skeletal system occurs during the initial infection via the lympho-haematogenous route. The radiographic features of cystic expansion have led to the name "Spina Ventosa" for tuberculous dactylitis of the short bones. We report a case of tuberculous dactylitis in the right little finger. CASE PRESENTATION: We describe a 36-year-old woman, who presented with a 12-month history of painless swelling of her right little finger associated with fever and night sweats. Her history was remarkable for persistent productive cough. On examination, her investigation reports and radiographs correlated with the symptoms of tuberculosis, suggestive of tuberculous arthritis. Magnetic resonance imaging of the hand was suggestive of osteomyelitis. Histopathological examination revealed chronic granulomatous inflammation that was consistent with osteomyelitis of the bone due to tuberculosis. However, acid-fast bacilli were not identified. Full course of anti-tuberculosis regimen was commenced. Monthly follow-up and radiographic examinations revealed improvement of the patient under this treatment. She also achieved a good functional outcome. CONCLUSION: Tuberculosis should be considered in patients with unusual soft tissue or skeletal lesions in order to make an early diagnosis and to achieve a good functional outcome. Although tuberculosis of the hand has a varied presentation, the majority of lesions respond to conservative treatment, as anti-tuberculosis chemotherapy is the cornerstone in the management of skeletal tuberculosis.

RESUMEN

BACKGROUND: Most information on bone-joint (BJ)-tuberculosis is based on data from high-incidence areas. We conducted a nationwide register-based analysis of BJ-tuberculosis in Denmark from 1994 to 2011. METHODS: We linked data from the national tuberculosis surveillance system on BJ-tuberculosis, hospital records, the Danish Hospital and Civil Registration System. RESULTS: We identified 282 patients with BJ-tuberculosis, 3.6% of all tuberculosis cases (n = 7936). Spinal tuberculosis was found in 153 of 282 patients (54.3%); 83.3% of all cases were immigrants. Danes were older and had higher Charlson comorbidity index scores than immigrants (P < .01). C-reactive protein and erythrocyte sedimentation rates were elevated in most cases. Median time to diagnosis after first hospital contact was 19.5 days for spinal tuberculosis and 28 days for other forms of BJ-tuberculosis (P = .01). Of patients with spinal tuberculosis, 54/133 (40.6%) had neurologic deficits at admission and 17.3% presented with cauda equina. Diagnosis was culture verified in 87%. (Resistance to any drug was found in 10.2%). Median time on antituberculous treatment for patients with spinal and other forms of BJ-tuberculosis was 9 months and 7 months, respectively (P < .01). Surgery was required in 44.4% patients with spinal tuberculosis and in 32.6% patients with other forms of BJ-tuberculosis (P = .04). Sequelae were reported in 57.5% of patients with spinal tuberculosis and 29.1% of patient with other forms of BJ-tuberculosis (P < .01). One-year mortality was 25.5% among Danes compared with 1.3% among immigrants (P < .01). CONCLUSIONS: BJ-tuberculosis was rare and seen mainly in younger immigrants in Denmark. More than half of cases were spinal tuberculosis, presenting with more severe symptoms and worse outcome, compared with other forms of BJ-tuberculosis.

RESUMEN

INTRODUCTION: Tuberculous involvement of metacarpals and phalanges is a rare presentation of extrapulmonary tuberculosis in adult. Tuberculous infection of the metacarpals, metatarsal and phalanges of hands and feet is known as tubercular dactylitis. CASE REPORT: A 65 years old female with history of pain and swelling at 1st metacarpal of left hand, since 3 months which gradual in onset and progressive in nature associated with multiple cervical swellings. While radiographs showed a pathological fracture of the 1st carpo-metacarpal joint (CMCJ) with soft tissue swelling, MRI revealed a large heterogenous lesion at the carpo-metacarpal joint of the thumb with bony erosions of the trapezium and 1st metacarpal base on T2W-STIR images. The lesion was extending upto the palmar aspect of the hand and displacing flexor pollicis longus tendon medially. During surgery, there was caseous material seen which was debrided and the fractured fragment was excised and sent for biopsy. The CMCJ was found to be unstable and a kirschner wire was used to stabilize the 1st CMCJ and immobilized in a POP splint. The biopsy of the fragment revealed tuberculous osteomyeltis. On follow-up the K-wire had backed out partially at the end of 5 weeks which was then removed and range of motion was started. At end of 1 year follow up the patient had little restriction of movement as compared to the opposite hand with no pain and hindrance in daily activity. CONCLUSION: The swelling subsided once Anti-Tubercular Treatment was started. The cervical lymphadenopathy also resolved over a period of 1 month.

RESUMEN

A man, aged 25 years, presented with pain, swelling, and drainage from the right clavicular area. He had a past history of abscess at the sternoclavicular joint. The cultures from the drainage site grew methicillin-sensitive Staphylococcus aureus, and he was placed on appropriate antibiotics. As S. aureus infection of the clavicle is often secondary in nature, particularly in adults, a thorough workup was done to identify the underlying cause. Quantiferon gold, done as a part of the workup, came back positive, while the bone cultures grew S. aureus and Mycobacterium tuberculosis. He was placed on 9 months of combination therapy for tuberculosis osteomyelitis with a good clinical outcome.

RESUMEN

Tuberculosis (TB) has become a rare disease in the developed countries but it is still a serious problem in developing countries. Incidence of tuberculous osteomyelitis of the jaw bones is very low. This rare incidence is the primary reason that this lesion gets mis-diagnosed many times. Here we report the diagnosis, treatment and follow-up of a case, which is a classical presentation of tuberculous osteomyelitis of mandible. Primary tuberculous osteomyelitis is a very rare entity but in the recent times, increased incidence of TB as a coinfection of HIV, has posed a big challenge in developing countries. If not diagnosed, at the right time, this can lead to serious complications like internal organ damage, tuberculous meningitis etc., Early diagnosis of tuberculous osteomyelitis will certainly reduce the morbidity of this disease condition.

RESUMEN

Se presenta un caso de infección tuberculosa con osteomielitis de clivus con afectación de tejidos vecinos y debut como cefalea refractaria sin clínica pulmonar. La osteomielitis tuberculosa de clivus es una entidad descrita en la literatura de forma excepcional y más propia de áreas con alta prevalencia de tuberculosis. Este caso debutó con clínica neurológica poco específica y se llegó al diagnóstico por el resultado del estudio microbiológico de nódulos pulmonares coexistentes sin clínica pulmonar asociada.

We report a case of tuberculous infection of exceptional location: clivus with involvement of surrounding tissues and refractory headache without pulmonary clinic. Tuberculous osteomyelitis of the clivus is a rare entity described in areas with highest tuberculosis prevalence. This case debuts with unspecific neurological symptoms and was diagnosed by the results of microbiological study of coexisting pulmonary nodules, without associated pulmonary clinic.

RESUMEN

Osteoarticular tuberculosis is a rare condition and it makes up 1-3% of all cases of tuberculosis. It usually occurs at the vertebra and it is common knowledge that tuberculous osteomyelitis is very rare at the foot. The clinical symptoms are nonspecific, and it can also mimic a wide range of pathologies, so it takes a lot of time to diagnosis and treat this illness. When osteoarticular tuberculosis is diagnosed, it should be gone through side to side with thorough debridement and chemotherapy. The author has experience 2 case of tuberculous osteomyelitis, so I report here on the diagnosis and treatment of this illness.

RESUMEN

Scrofuloderma results from a direct extension of an underlying tuberculosis focus such as the lymph node, bone or joint to the underlying skin, and is often associated with pulmonary tuberculosis. One 72-year-old man presented with erythematous swollen patch with scales on the left hand and erythematous swollen patch on the left elbow. He had tuberculous osteomyelitis of left elbow. And another patient who is a 59-year-old man presented with hemorrhagic, purulent ulcers with crust and exudate on the left and right chest. Each size of ulcers are 6.0x5.0cm and 5.0x5.0cm. He had reactive pulmonary tuberculosis and tuberculous spondylitis. Biopsy specimens from the skin showed lymphocytes, epitheloid cells, and Langerhan's giant cells with caseation necrosis. Acid-fast bacilli were identified on AFB staining. We report two unusual cases of scrofuloderma associated with tuberculous osteomyelitis and pulmonary tuberculosis respectively.
