INSULINOMA - DIAGNOSIS WITH FAT-SUPPRESSED MR-IMAGING

Insulinomas are the most common secretory tumors of the pancreas. They manifest early in their natural history because of their hormonal activity. Commonly, the diagnosis of insulinoma is based on clinical and laboratory data. The classic scenario in which the clinician tells the radiologist, ''The patient has an insulinoma-please find it,'' still holds true. Because insulinomas often become evident when they are quite small, several imaging techniques may be required for identification. We report a case of pancreatic insulinoma diagnosed clinically and located radiologically with fat-supressed MR imaging.
