technetium-tc-99m-sulfur-colloid and Ileal-Diseases

The use of radionuclide gastrointestinal scanning with 99mTc sulfur colloid, supplementing angiography, is described in the diagnosis of the source of bleeding in a 60-year-old woman with neurofibromatosis. These two procedures succeeded in locating the origin of bleeding from neurofibroma in the jejunum, which was corrected by surgery. To our knowledge, this case report is the first description of a patient with neurofibromatosis, with all the reported gastrointestinal symptoms: intermittent abdominal pains, palpable abdominal mass, gastrointestinal bleeding and small bowel obstruction.

99mTc sulfur colloid scintigraphy is a technique which can be used to localize sites of lower gastrointestinal hemorrhage. Two reports of patients illustrate its use clinically. This procedure is non-invasive, relatively inexpensive, easily performed and has a high degree of sensitivity. The technique may, in some instances, replace angiography or endoscopy as the initial procedure used to diagnose the site of lower gastrointestinal bleeding or, more likely, serve as a complementary diagnostic modality.
