Oct 10, 2024 · Rice bodies are multiple small loose intra-articular bodies that macroscopically resemble polished grains of white rice. They are located in the synovial fluid, bursae or tendon sheaths 4.

Rice bodies are tiny, uniformly shaped and sized bodies composed of fibrin, which are hypointense on T2, intermediate in signal intensity on T1 and contain no mineralization. It is proposed that synovial cells undergo infarction, are shed into the joint, and become encased by fibrin over a period of time.

Rice bodies are free corpuscles of synovial origin with a cartilage-like appearance that may reach hundreds in number in the intra-articular space. Rheumatologic or infectious pathologies that may produce synovial hypertrophy play a major role in the etiology.

Rice bodies in the wrist are a rare finding commonly associated with a chronic microinflammation of the synovium either in the context of rheumatoid arthritis or chronic infections. The diagnosis can be made through proper history, physical examination, and intensive radiological assessment.

Multiple loose bodies and multiple tiny loose signals are seen distributing within the effusion-fluid, consistent with rice bodies. Rice bodies may be seen in arthritis (as rheumatoid arthritis), chronic synovitis and chronic bursitis.

May 28, 2024 · Rice body formation in the hip joint is a rare occurrence, typically linked to prolonged inflammation from conditions like arthritis and chronic inflammation. A 41-year-old male patient successfully underwent surgical removal of rice bodies from the hip, resulting in complete symptom resolution and no recurrence over a two-year follow-up period.

Plain MRI scanning revealed that in the left knee cavity and the popliteal fossa area, a large number of low signals on free rice‐like bodies were visible inside and the lower femur and the upper tibia exhibited abnormally high signals of patchy lipography.

If detected in the knee joint, rice bodies are clinically and radiologically confused with synovial chondromatosis. Preoperative radiographs showing no calcific masses and MRIs showing free intra-articular or intrasynovial tiny bodies are characteristic findings of rice bodies.

Initially identified in a tubercular infection, rice bodies are found in various inflammatory processes such as arthritis (rheumatoid, juvenile, seronegative, and septic arthritis), traumatic injuries, chronic bursitis, and within tendon sheaths.

Rice bodies are mainly formed of fibrin and are seen in relation to joints, bursa or tendon sheaths in patients with rheumatoid arthritis, tuberculosis or tenosynovitis. Although rice bodies in relation to tuberculosis of large joints like knee are rarely reported, our case demonstrates that they can be seen even in large joints.
