An Uncommon Ischial Tuberosity Tuberculosis Infection

INTRODUCTION: Ischium is one of the rare sites to be involved by mycobacterium tuberculosis. The incidence is generally not more than 0.2% in any of the large series. We report an unusual case of extrapulmonary tuberculosis of the ischial tuberosity presenting with chronic gluteal pain of 6 months duration. CASE REPORT: A 35-year-old male patient presented with chronic dull aching gluteal pain of 6 months duration, for which lifestyle modifications and rest were advised initially. Antituberculosis chemotherapy was administered (for a period of 1 year) following histopathological confirmation of tuberculosis. At 1 year post antitubercular therapy, the patient had no pain and was symptom free. Furthermore, radiographs showed healed right ischial tuberosity osteomyelitis. CONCLUSION: Tuberculosis involving the ischial tuberosity is rare. The early diagnosis is mandatory for good results, and with a worldwide resurgence of the disease, a high index of suspicion is necessary. Prompt diagnosis and treatment resulted in a good clinical outcome in this patient.
