Abstract
Multifocal osteoarticular tuberculosis is uncommon and accounts for approximately10% of all cases of osteoarticular tuberculosis. Concomitant vertebral and iliac bone tuberculosis has not been reported in the literature to date. We report one such case for its unusual clinical and radiological presentation, which had presentation more similar to a malignant bone tumour than an infection. Skeletal tuberculosis, multifocal osteoarticular tuberculosis.

We report the case of a patient with lumbar vertebral and iliac bone tuberculosis presenting as a malignant bone tumour rather than infection
Osteoarticular tuberculosis accounts for 2% of patients with tuberculosis with the most common site being the spine (50%), and the second most common being the hip joint (20%) followed by the knee joint (10%)
Summary
Osteoarticular tuberculosis is uncommon and accounts for 2% of all cases of systemic tuberculosis 1. While 50% of osteoarticular tuberculosis occurs in the vertebral column, less frequently affected sites are the hip, knee and sacroiliac joints 1. The multifocal form of skeletal tuberculosis is exceptional, with a rate of 10% of all skeletal tuberculosis cases even in countries where the disease is endemic .1,5. Multifocal skeletal lesions may occur as a result of hematogenous dissemination from another primary focus such as cervical lymph nodes, lungs, tonsils or gastrointestinal tract. Iliac bone tuberculosis is rare and presentation with concomitant vertebral tuberculosis is even more rare, and has not been reported to date in the literature. We report the case of a patient with lumbar vertebral and iliac bone tuberculosis presenting as a malignant bone tumour rather than infection
