A 65-year-old woman presented at our hospital with the symptom of bloody stool. Esophagogastroduodenoscopy and colonoscopy showed no bleeding lesion. Abdominal CT scan and MRI showed a mass in the pelvic cavity which close to the ileum. Capsule endoscopy revealed hemorrhagic enteritis of the ileum. We considered that the mass is the cause of enteritis of the ileum. The operation was performed to diagnose and treat. The mass was abscess, adhering to the ileum and the right ovary. We peeled adherence to the ileum and extract the abscess and the right ovary. After the operation, anemia and bloody stool were disappeared and capsule endoscopy showed no bleeding lesion in the ileum.
