We report a case of true enterolithiasis caused by radiation enteritis. A 69-year-old woman undergoing radical hysterectomy and radiotherapy for uterine cervix cancer 28 years earlier and suffering lower abdominal pain in January 2006 was found in contrast-enhanced computed tomography (CT) to have ileal stenosis and calculus in the dilated ileum oral to the stenosis underwent resection of the stenotic and dilated ileum. Pathological study of resected specimens showed radiation-induced fibrous change. Stenosis was thought to be due to an ulcer scar due to radiation enteritis. Bile acid was a component of calculus. Radiation enteritis should be considered as a differential diagnosis, despite the long decades since radiotherapy. Radiation enteritis presents various conditions and enterolithiasis may be one complication.
