A 73-year-old woman presented with intermittent abdominal pain and weight loss of 15 kg for 2 years. Colonoscopy revealed an erythematous polypoid tumor with a long and wide stalk in the cecum, but with air inflation, it abruptly went away through the ileocecal valve (ICV). An abdominal computed tomography showed a well-demarcated pedunculated subepithelial mass of 2.6×2.7 cm size with fat attenuation in the terminal ileum. It was an intussusceptum of the ileal lipoma through the ICV. This ileal lipoma was causing her symptoms because repeated ileocolic intussusceptions resulted in intermittent intestinal obstructions. In order to avoid surgical sequelae of ileal resection, snare polypectomy using cap-assisted colonoscopy technique was performed within the ileum without complications. The histopathology report confirmed it as a subepithelial lipoma. After endoscopic resection of the ileal lipoma, the patient has been free of symptoms and was restored to the original weight.

Xanthogranulomatous inflammation (XGI) is a rare benign inflammatory disease characterized by aggregation of lipid-laden foamy macrophages. This disease entity has been described in various organs but most commonly in the kidney and gallbladder. The occurrence of this disease in the lower gastrointestinal tract is extremely rare. Its clinical importance is that it can be misdiagnosed as an infiltrative cancer. In this case report, a 52-year-old male complained of right lower quadrant abdominal pain for a period of 3 months. Abdominal computed tomography revealed appendiceal mass and colonoscopy revealed multiple erythematous nodular lesions in the terminal ileum and appendiceal orifice, mimicking appendiceal cancer. Right hemicolectomy was done and the pathological specimen revealed XGI of the terminal ileum. To our knowledge, this is the first case of XGI in terminal ileum presenting as abdominal pain and the appendiceal mass on radiologic findings.

Ileal Dieulafoy lesion is an unusual vascular abnormality that can cause gastrointestinal bleeding. It can be associated with massive, life-threatening hemorrhage and requires urgent angiographic intervention or surgery. Ileal Dieulafoy lesion is hard to recognize due to inaccessibility and normal-appearing mucosa. With advances in endoscopy, aggressive diagnostic and therapeutic approaches including enteroscopy have recently been performed for small bowel bleeding. We report two cases of massive ileal Dieulafoy lesion bleeding diagnosed and treated successfully by single balloon enteroscopy with a review of the literature.
