technetium-tc-99m-sulfur-colloid and Intussusception

Complications arising from Meckel's diverticulum are uncommon in adults and are seldom, if ever, seen in the elderly. When they do occur in adults, intestinal obstruction or inflammation is the usual mode of presentation, hemorrhage being much less common. The patient described in this case report was 78 yr old, presented initially with iron deficiency anemia and, later, developed severe acute hemorrhage. The cause of the hemorrhage was ulceration at the tip of an invaginated Meckel's diverticulum. The ulceration was not peptic in origin, as is usually the case in similar presentations in children, no ectopic oxyntic mucosa being detected in the diverticulum of our patient. In previous reports, invaginated Meckel's diverticula have always been accompanied by intussusception, and abdominal pain has been an important part of the symptom complex in such patients. Our patient had no abdominal pain, and no intussusception was noted at surgery. This case emphasizes the need for considering a Meckel's diverticulum as the source of acute or chronic hemorrhage, irrespective of the patient's age. The utility of radionuclide blood pool imaging in arriving at a diagnosis in these cases is discussed.

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.
