technetium-tc-99m-sulfur-colloid and Intestinal-Neoplasms

This is a case report of a patient with an initial diagnosis of chronic pancreatitis who actually had metastatic carcinoid tumor. His symptoms of abdominal pain, weight loss, and diarrhea were manifestations of the large tumor bulk within the liver as well as carcinoid syndrome. Although abdominal CT scans showed multiple liver lesions, the primary lesion was not identified by conventional imaging studies. However, the mid-gut primary lesion was visualized on in-111 labeled octreotide scintigraphy; where the liver lesions were better delineated and seen to be separate from the normal pancreas when the Tc-99m sulfur colloid images were compared to the octreotide images.

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.
