Radiation enteritis diagnosed through capsule endoscopy, an uncommon cause of iron-deficiency anemia.

A 66-year-old woman was operated on in 1988 for an endometrial adenocarcinoma, after which she received adjuvant radiotherapy. The patient presented with 6month, progressive iron-deficiency anemia. A complete endoscopic study (esophago-gastrosco-duodenoscopy and ileocolonoscopy) was performed; mucosal edema with superficial whitish spots in the terminal ileum (fig. 1A) was observed. Nonspecific chronic inflammation was reported in the histology study. To evaluate extension and small bowel involvement, a video capsule endoscopy was indicated. Diffuse and continuous involvement of the mucosa from the proximal jejunum to the terminal ileum was detected. The mucosal lesions ranged from mild edema with preservation
