Abstract

Multiple rice bodies are commonly observed in various rheumatologic disorders and tuberculous arthritis, but rice bodies are rarely observed in nonspecific synovitis without any underlying disease. We performed arthroscopic rice body removal and synovectomy for nonspecific synovitis with multiple rice bodies in a 31-year-old male patient, and the results were satisfactory. No evidence of underlying disease, including rheumatoid arthritis or tuberculous arthritis, was observed during 2 years on the follow-up evaluations after the arthroscopic procedure. There have been very few confirmed rice bodies cases without underlying disease, so making a careful differential diagnosis to rule out rheumatologic and infectious disorders is required to avoid possible aggravation of disease, which may result in persistent articular cartilage destruction.
