Tuberculous Trochanteric Bursitis Mimicking Hydatidosis: A Rare Case Report.

Tuberculous trochanteric bursitis is a rare condition that accounts for less than 2% of musculoskeletal tuberculosis cases, usually diagnosed late because of reduced diagnostic suspicion, and the insidious clinical presentation aspect of musculoskeletal tuberculosis. We describe the case of a 26-year-old male presenting with a slowly enlarging painful mass of the right hip without systemic symptoms. Imaging initially suggested hydatidosis, but aspiration confirmed Mycobacterium tuberculosis. A complete bursectomy combined with antitubercular therapy led to full recovery with no recurrence at two years. This case highlights the diagnostic challenges of tuberculous trochanteric bursitis, often mimicking other pathologies, and underlines the importance of early suspicion, histopathological confirmation, and combined surgical and medical treatment for optimal outcomes.
