Key clinical message Tenosynovitis with rice bodies is a rare presentation, diagnosable by MRI. Surgical excision is the preferred treatment for tendon sheath masses containing rice bodies. The etiology was Mycobacterium tuberculosis in our case, highlighting the need to consider extrapulmonary TB in atypical presentations, ensuring effective treatment. Abstract Rice body tenosynovitis is a rare clinical phenomenon with various etiologies. Inflammatory diseases such as rheumatoid arthritis and tuberculosis have been shown to be associated with this condition. Herein we report a 46‐year‐old male who presented with multiple masses of the dorsal and volar aspects of the left wrist. The masses did not cause significant pain or limitation of motion. Magnetic resonance imaging showed the presence of numerous hypointense bodies in the masses. During the surgical procedure, separate cysts originating from the synovitis of both the extensor and flexor compartments were identified along with white rice bodies within them. Masses were excised and Xpert MTB/RIF assay on the rice bodies was conclusive of M. tuberculosis (TB). The patient was discharged on anti‐TB medications with no complication or recurrence after 1 year of follow‐up.
