Tuberculous osteomyelitis of the mandibular condyle: A rare case report and review of the literature

Tuberculosis (TB) is a chronic infectious granulomatous disease caused by the air-borne bacillus Mycobacterium tuberculosis and less frequently by other bacteria in the M. tuberculosis complex (Mycobacterium Bovis and Mycobacterium africanum). Tuberculous osteomyelitis of the condyle may present atypical clinical findings akin to temporomandibular joint arthritis or middle ear infections. A detailed clinical and radiographic examination aided by a histopathological and a microbiological diagnostic workup is the key to timely detection and administration of appropriate therapeutic regimens. A high degree of clinical suspicion is thus advocated in patients with such atypical presentations. We, hereby, are presenting a rare case of tuberculous osteomyelitis in a 15-year-old female child.

Tuberculous osteomyelitis of proximal fibula: An unusual presentation of tuberculosis

Tubercular involvement of the proximal fibula is rare. We present a case of tuberculosis of proximal fibula in an immunocompetent 22-year-old female. She was diagnosed clinically as a case of cellulitis. Radiological investigations, including magnetic resonance imaging revealed a destructive lesion in her right proximal fibula. Finally, by fine-needle aspiration cytology and GeneXpert polymerase chain reaction, a diagnosis of tuberculous osteomyelitis of proximal fibula was established. She was managed non-operatively with multidrug antitubercular chemotherapy. A high index of suspicion is required to make a diagnosis of musculoskeletal tuberculosis of such a rare site in the early stages.

Chronic Multifocal Osteomyelitis – Is Mycobacterium avium Complex Really the Culprit? A Case Report in an Adult Female

Introduction:There are reports which describe multiple lytic lesions seen on X-ray resulting from a non-tuberculous Mycobacterium skeletal infection in immunocompetent adults and children. AdditionallyIn addition, similar multifocal lesions have also been described in chronic recurrent multifocal osteomyelitis (CRMO) which is more common in children but has have rarely been reported in adults. We present a case of a 47-year-old female who presented with multiple osteolytic lesions and discuss how her diagnosis overlaps with CRMO and multifocal non-tuberculous osteomyelitis associated with Mycobacterium avium complex (MAC). Case Report:A 47-year-old female presented with a mass at her left sternoclavicular joint. Biopsy of the lesion showed acute and chronic inflammation suggesting osteomyelitis. The patient was on intravenousIV antibiotics with some improvement. After three 3 ½ and a half months, she was having knee pain and imaging showed another lesion and a bone scan found a third. Delayed cultures grew Mycobacterium avium complexMAC but ultimately the patient improved when she was taking naproxen for multifocal osteomyelitis. Conclusion:Multifocal lytic lesions on imaging in an adult can be multifocal osteomyelitis that, like in pediatric patients, may be treated best with nonsteroidal anti-inflammatory medications as with the patient in this case.

BCG Vaccine Induced Tuberculous Osteomyelitis of Left Distal Femur in a Young Child: Case Report and Literature Review

Tuberculosis (TB) is an essential problem for healthcare systems especially in developing countries. TB continues to pose a significant global health burden [1]. Bacillus Calmette-Guérin (BCG) is an important vaccine used to prevent Tuberculosis (TB), especially meningeal TB and disseminated TB disease in children [2]. BCG is prepared from live bovine tuberculosis bacillus, and is given to protect against TB. Although vaccination against TB by means of BCG is widespread all over the world and is generally considered to be safe, but serious adverse reactions can occur. These may be minor such as abscess formation or skin ulceration at the site of vaccination to major adverse reaction such as fatal disseminated infection especially in patients with immune deficiency [3]. These adverse reactions after BCG vaccination depend on the BCG dose, vaccine strain, vaccine administration method, injection technique, and recipient’s underlying immune status [4]. The aim of this case report is to point out that clinical suspicion of BCG-induced osteomyelitis is warranted in pediatric patients with chronic symptoms of pain, limping, swelling and a limited ROM in the extremity. We also aimed to remind that imaging and culture studies may guide the clinician although tissue biopsies and genetic tests can confirm the histopathology and to review related articles.

Combined Pyogenic and Tuberculous Osteomyelitis of the Clavicle: A Case Report

Introduction: Tuberculous osteomyelitis of the clavicle accounts for 1–3% of cases of osteoarticular tuberculosis. It presents with non-specific symptoms and may have superadded infections with pyogenic organisms, requiring a high degree of suspicion to adequately diagnose and initiate appropriate treatment. Case Report: We describe a case of a 35-year-old male with osteolytic clavicular lesion and abscess in the supraclavicular fossa. Tissue diagnosis revealed tuberculous osteomyelitis with superadded infection with Staphylococcus aureus. He was managed with debridement and anti-tubercular therapy. Conclusion: A high degree of suspicion is required to adequately test and diagnose the cause of osteomyelitis of the clavicle, in the absence of a predisposing event, as staphylococcal and tuberculous infection can present simultaneously. Keywords: Clavicle, tuberculosis, osteomyelitis.

Difficulties associated with the diagnosis of tuberculous osteomyelitis of the ribs in children

Diagnosis of tuberculosis in children is challenging because of variable clinical symptoms and no specific signs. We report a case of tuberculous osteomyelitis of the ribs, which demonstrates difficulties associated with the diagnosis of generalized tuberculosis in an 8-year-old child (correct diagnosis was established after 1.3 years). Diagnostic procedures included: Mantoux test, skin test with recombinant tuberculosis allergen, computed tomography, pathomorphological and bacterioscopic testing. The patient presented with disease progression and lesions to the lung tissue, pleura, and ribs and did not respond to antibacterial therapy, hormones, and cytostatics. This required repeated diagnosis revision. The diagnosis of tuberculosis of the right 4th and 5th ribs was confirmed after surgery using bacterioscopic and immunohistochemical examinations. The child received comprehensive treatment in a specialized tuberculosis hospital and had positive dynamics. Despite the correct routing, low suspicion for tuberculosis in primary and secondary healthcare institutions has led to an insufficient use of currently available diagnostic methods and late diagnosis of tuberculosis in a child residing in a megapolis.
