Tuberculous subdeltoid bursitis with rice bodies.

A 41-year-old woman with a 2-month history of diffused swelling and persistent dull pain in her right shoulder was examined. Magnetic resonance imaging (MRI) findings revealed subdeltoid bursitis and rice bodies with normal surrounding tissue and shoulder joint. Arthoscopic debridement and biopsy of the subdeltoid bursa were performed. Histologic examination of the bursal tissue showed granulomatous tissue with typical caseous necrosis. A positive culture of Mycobacterium tuberculosis confirmed the diagnosis of tuberculosis. We report on the clinical, radiological and athological findings in a patient with tuberculous subdeltoid bursitis accompanied by multiple rice body formation without coexisting active bone and joint tuberculosis, and conduct a literature review.
