| description | Insulinomas are rare endocrine tumors with an estimated incidence of 1(one) per million. Optimal therapy for all islet tumors of the pancreas is curative surgical resection. However, previous reports have show that, in the absence of preoparative localization, insulinoma may not be found intraoperatively in about 20% of patients. With current imaging technology, including serial computed tomography (CT), magnetic resonance imaging (MRI) and ultrasonography, localization of insulinomas less than 2cm remains inadequate. This case report shows that selective intraarterial calcium injection with hepatic venous sampling for insulin levels measured is a efficient technique for the localization of insulinomas. |
