Abstract
A 51-year-old woman presented with recurrent bleeding per rectum. Her earlier endoscopies were negative. Tc-99m RBC GI bleeding scintigraphy was performed. It demonstrated an apparent hypervascular pelvic mass, and active small bowel bleeding. Based on scintigraphic finding of a predominant pelvic mass indicating tumor, CT of the abdomen and pelvis was performed for further gastrointestinal bleeding localization work up instead of an invasive angiography or endoscopy, which detected a small bowel tumor in the pelvis. A small bowel gastrointestinal stromal tumor was resected subsequently.
