Gluteus maximus abscess revealing a tuberculous arthritis: A case report and review of the literature.

Although tuberculosis is a widespread disease in Morocco, musculoskeletal form is relatively rare and even rarer when affects the sacroiliac joint. Tuberculous sacroiliitis remains a challenge for orthopedists owing to its insidious onset and non-specific clinical presentation. Herein, we report the case of a 23-year-old male with a growing mass in his left gluteal area, diagnosed with tuberculous sacroiliitis, based on bacteriological and histological findings. The aim of our work is to draw attention to the importance of continued awareness for early detection and adequate treatment of this very rare entity.
