Abstract
The risk of tuberculosis (TB) increases in immunocompromised patients. Multiple myeloma is considered a risk factor for TB and myeloma patients with TB have a higher mortality rate than those without TB. Herein, we report a case of concomitant TB of the iliotibial band mimicking a soft tissue tumor and tuberculous trochanteric bursitis in a patient with multiple myeloma. In this article, the characteristic magnetic resonance imaging (MRI) findings were low T2 signals in the cystic fluid lesion, a dark T2 signal rim, and peripheral rim enhancement. These results could help differentiate TB of the iliotibial band and trochanteric bursitis from other pathologies. If the abovementioned findings were observed in immunocompromised patients, extrapulmonary TB may be expected even if chest radiographs are normal.
