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.
免疫功能低下的患者发生结核病（TB）的风险增加。多发性骨髓瘤被认为是结核病的危险因素，且患有结核病的骨髓瘤患者的死亡率高于未患有结核病的患者。在此，我们报告一例多发性骨髓瘤患者同时发生髂胫束结核，类似于软组织肿瘤和结核性转子滑囊炎。在本文中，特征性磁共振成像（MRI）表现为囊性病变中低 T2 信号、暗 T2 信号环和周围边缘增强。这些结果有助于将髂胫束结核和转子滑囊炎与其他病变区分开来。如果在免疫功能低下的患者中观察到上述表现，即使胸部 X 线片正常，也可能预期为肺外结核病。
