  • Abstract
  • Look Inside

 The patient was a 49-year-old woman with a chief complaint of a “floating” sensation, who was referred to us and admitted because of anemia and melena. Colonofiberscopy (CF) revealed fresh blood in the colon and terminal ileum, but no lesion was detected. Because air had been introduced into the small intestinal tract by CF, 3D-CT of the abdomen was performed immediately after CF in order to examine the small intestine. A tumor with a long diameter of approximately 9 cm was discovered, and virtual endoscopy (VE) revealed that part of the tumor was protruding into the lumen of the ileum and that there was a depression in its tip. Based on these findings, a submucosal tumor of the ileum with bleeding from the site was suspected and, because the bleeding had persisted, emergent surgery was performed on the same day. A gastrointestinal stromal tumor (GIST ; uncommitted type) was found in the ileum 50 cm proximal to Bauhin's valve. VE was useful in diagnosing this tumor manifested by bleeding from the small intestine.
