Distinguishing multiple rice body formation in chronic subacromial-subdeltoid bursitis from synovial chondromatosis

Skeletal Radiol. 2002 Feb;31(2):119-21. doi: 10.1007/s002560100412. Epub 2001 Sep 5.


Multiple rice body formation is a complication of chronic bursitis. Although it resembles synovial chondromatosis clinically and on imaging, the literature suggests that analysis of radiographic and MR appearances should allow discrimination. We report the imaging findings in a 41-year-old man presenting with rice body formation in chronic subacromial-subdeltoid bursitis. We found that the signal intensity of the rice bodies is helpful in making the diagnosis.
