Abstract

The insulinoma; functional beta cell tumor of the pancreas; is charaterized by frequent attacks of fasting hypoglycemia; which arise from varying degrees of neuroglycopenia and ofen lead to misdiagnosis as a neurologic or psychiatric disorder. During laparatomy; the tumor was found at a posterior part of head of pancreas; measuring 1.2X0.8cm; tumor resection was performed. In the follow up study for 8 months; he has had no hypoglycemic symtoms till now. Small insulinoma may be undetectable by arteriography or C. T scanning. They can be identified by palpation during laparatomy or by the point at which high insulin levels are detected in the venous effluent sampled at several sites by catheterization of the splenic and portal veins. We report a case of insulinoma; which preoperatively identified by serial measurement of blood glucose; insulin level and c-peptide suppression test.
