technetium-tc-99m-sulfur-colloid and Neurofibromatosis-1

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.

The authors describe the lymphoscintigraphic findings in a 4-year-old child with neurofibromatosis, the principal manifestation of which was elephantiasis neuromatosa involving the right lower extremity. The lymphoscintigram demonstrated dilated lymphatics and enlarged lymph nodes.
