Primary tuberculosis of the clavicle.

Abstract

Tuberculosis of the clavicle is a rare lesion, accounting for less than 1% of all osteoarticular tuberculosis. The lesion has been described in a few case reports. The lesion can have a varied presentation, ranging from dull, aching pain to bony swelling and a draining sinus. The rarity of the lesion, its nonspecific symptoms, and its striking resemblance to common cystic conditions such as bone tumors and metabolic conditions such as rickets make diagnosis difficult. The authors describe a series of 17 patients with primary tuberculosis of the clavicle. Radiographs and magnetic resonance images were obtained for all patients, and a preliminary diagnosis was made on the basis of clinical features and the results of erythrocyte sedimentation rate, C-reactive protein, and Mantoux tests. Erythrocyte sedimentation rate was uniformly elevated. Radiographs showed diffused thickening and honeycombing, eccentric expansile lytic lesions with surrounding osteopenia, or sequestration not unlike pyogenic infection. Magnetic resonance imaging is useful for determining the extent of the lesion and soft tissue involvement. The radiological and laboratory findings provided complementary information. The diagnosis was confirmed on biopsy material that was analyzed with histopathology, pus culture and sensitivities, gram stain, acid-fast stain, and cultures on Löwenstein-Jensen medium. Patients were treated with multidrug antitubercular chemotherapy for 18 months and were assessed on pre- and posttreatment radiology, erythrocyte sedimentation rate, and University of California, Los Angeles (UCLA) shoulder rating scale. The results of conservative management of tubercular osteomyelitis were uniformly good, and all patients recovered well.
