18F-Fluorodeoxyglucose PET in a patient with primary small bowel lymphoma: the only sensitive method of imaging.

This report describes the case of a patient with primary small bowel lymphoma. Well-established methods of imaging did not give a hint on diagnosis. Increased 18F-fluorodeoxyglucose uptake was visualized on performance of positron emission tomography, corresponding with the intraoperatively found tumorous process. The present case points to a potential superiority of positron emission tomography in visualizing primary small bowel lymphoma.
