Incidental abnormalities detected during scintigraphy for gastrointestinal bleeding.

The authors describe a number of abnormalities that were incidentally found in a series of 132 scintigraphic studies performed for acute gastrointestinal hemorrhage. These incidental abnormalities involved the vascular system, reticuloendothelial system, and soft tissues. Correlative radiographs and computed tomographic scans are presented for some cases. The authors explore the potential impact of these abnormalities on subsequent patient evaluation and care, including radiologic workup.
