Images from patients with small bowel strictures. A-C, Images from a 69-year-old woman with chronic iron-deficiency anemia and negative findings on colonoscopy. Computed tomographic enterography revealed multiple short-segment ileal strictures (A and B, arrows) indicative of nonsteroidal anti-inflammatory drug (NSAID) enteropathy, with subsequent retrograde enteroscopy (C) confirming and dilating NSAID diaphragms. D, Computed tomographic enterographic image from a 49-year-old woman with transfusion-dependent iron-deficiency anemia demonstrating short-segment ileal strictures (arrows), thought to represent NSAID enteropathy or Crohn disease, with subsequent single balloon endoscopy confirming ileal strictures with ulcerations. E, Computed tomographic enterographic image from a 58-year-old woman with a history of radiation therapy for anal cancer and iron-deficiency anemia showing long-segment ileal strictures in multiple phases of enhancement (arrows) thought to represent radiation enteropathy. Subsequent abdominal exploration at another institution for retained capsule endoscopy demonstrated multiple adhesions and radiation enteritis.
