Rice bodies in ischiogluteal bursitis
Statistics from Altmetric.com
A 58 year old woman with rheumatoid arthritis suffered from pain and swelling in the right buttock. The pain was greatly aggravated by sitting. Computed tomography and magnetic resonance imaging (MRI) revealed a cystic mass lesion with thick wall, adjacent to the right ischial tuberosity and gluteus maximus muscle. On T2-weighted MRI, the mass contained multiple hypointense small nodules, indicating rice bodies (fig 1). Total resection was performed and histopathological findings were compat
ible with chronic bursitis; rice bodies consisted of dense fibrinous material.
