Abstract:
Herein is a report of a patient with gastrointestinal stromal tumor (GIST) possibly arising from greater omentum accompanying diffuse peritoneal disseminatation. Positron emission tomography (PET) with 18F-fluorodeoxyglucose (18F-FDG) revealed that 18F-FDG uptake was widely spreading in the abdomen. In this case, the PET image was more useful than computed tomography (CT) for understanding tumor distribution rather. PET provides important information on tumor distribution and has an impact on evaluating clinical stage in GIST patients.
