Rice Bodies Accompanied by Tenosynovitis of the Wrist: A Case Report and Literature Review

Rice bodies, a rare finding in clinical practice, are commonly observed in the shoulders and knees of affected individuals. However, they can occur in the wrist as well. Herein, we report a case of a female presenting with painful swelling in the right wrist that lasted with a history of carpal tunnel syndrome, rheumatoid arthritis, and history of median nerve decompression two years ago. A potential diagnosis of infectious diseases and gout was excluded through negative cultures and laboratory findings. X-rays showed no significant findings; however, magnetic resonance imaging revealed findings suggestive of rice bodies that were confirmed by additional proton dense fat-saturated imaging. The mass was then removed by extensive debridement and sent for pathological assessment, which showed multiple nodules containing fibrin and polymorphonuclear cells. The patient did not experience recurrence during the follow-up period. Rice bodies, although rare, can occur in the wrist, and this imposes several challenges associated with their diagnostic and management protocols.
