A rare cause of acute gastrointestinal hemorrhage: ileal lipoma

Abstract

Primary small bowel tumors account for 1-6% of all Gastrointestinal (G.I.) tract malignancies. Among these pedunculated lipomas are unusual. We report a case of a 66-year-old male with a history of G.I. hemorrhage and acute anemia, negative upper and lower endoscopies and a pedunculated lipoma in distal ileum, revealed by CT enterography. The patient was successfully treated by open surgery. Patients with G.I. hemorrhage and negative upper and lower endoscopies need an accurate evaluation of small bowel. Multislice CT enterography or Magnetic Resonance enteroclysis/ enterography represent the fastest and more accurate tools to obtain an exhaustive evaluation of small bowel. In case of small bowel tumors this diagnostic procedures can show site and stage and can even suggest histological type of such neoplasms, with a significant impact in the surgical planning, avoiding time consuming surgical exploration. In this patient multislice TC enterography allowed a correct diagnosis of benign lipoma due to its radiological density and absence of infiltration of the intestinal wall and surrounding tissues.
