There is moderate to gross synovial hypertrophy with effusion and mobile echoes involving glenohumeral joint as well as subacromial-subdeltoid bursa. There is full thickness, a full-width defect involving the supraspinatus tendon with retraction about 28 mm. Long head biceps, subscapularis and infraspinatus tendons are intact. There are multiple erosions involving articular surface of the humeral head. Supraspinatus and infraspinatus muscles show mild to moderate fatty infiltration as well as atrophy.

Case Discussion
An elderly female presented with a history of treatment taken for pus discharge from the anterior aspect of the right shoulder a few months back. She developed right shoulder region diffuse swelling and restricted right shoulder movements for last 1 month. Radiograph and ultrasound favor glenohumeral osteomyelitis; possibly tuberculous etiology. Open biopsy and synovectomy were done. Histopathology revealed tuberculosis.
