Abstract
A 61-year-old female was admitted to our hospital due to leg purpura and renal dysfunction. After admission, she complained of abdominal pain and melena. A double-balloon enteroscopic study revealed multiple ulcers in the distal ileum. We suspected arteritis syndrome, and started to treat the patient with a corticosteroid. However, we could not control the intestinal bleeding, even when abdominal arteriography was performed. Fluoroscopy revealed widespread inflammation of the small intestine. Therefore, we performed ileocecal resection. The pathological diagnosis was polyarteritis nodosa. In cases of uncontrolled hemorrhagic enteritis, arteritis including polyarteritis nodosa can be diagnosed early with endoscopy. On the other hand, fluoroscopy is useful for detecting widespread inflammation of the small intestine.
