Bleeding Meckel's diverticulum presenting as focal extravasation on pertechnetate scintigraphy.

The evaluation of gastrointestinal hemorrhage may include a Meckel's scan, particularly in children. Typically, a Meckel's diverticulum shows discrete, focal uptake in the right lower abdomen. The authors describe an adult whose bleeding Meckel's diverticulum manifested as brisk, intermittent intraluminal tracer extravasation.
