The small bowel angiodysplasia is a rare entity that causes lower intestinal bleeding; the diagnosis is difficult and based on selective angiogram. In our case, an 85-year-old woman was hospitalized after frequent episodes of melena. We performed an enema-helical CT abdominal examination before and after contrast medium administration per venam, detecting some increased intensity areas that surgery confirmed to be a vascular dysplasia on the jejunal first loop. We found the source of hemorrhage without performing an angiographic examination.
