RESUMEN
We report a 40-year-old female patient with clinical findings suggestive of insulinoma. Although imaging studies did not reveal any tumors in the pancreas, a selective arterial calcium stimulation test(SACI), procedurally simpler and more effective than transhepatic pancreatic venous sampling, was performed. And then near total pancreatectomy was carried out because the possibility of small insulinoma could not be completely excluded. Grossly, the surgically removed pancreas did not reveal any tumors. However, the pancreas exhibited islets cell hyperplasia. To our knowledge, this is the first reported authentic case in a Korean adult of islet-cell hyperplasia diagnosed by selective arterial calcium stimulation test.

A 72-year-old man who had suffered several episodes of syncope was diagnosed as having hyperinsulinemic hypoglycemia. Although imaging studies and percutaneous transhepatic portal venous sampling did not reveal the existence of any tumors in the pancreas, distal pancreatectomy was performed because the possibility of a small pancreatic endocrine tumor could not be completely rejected. External examination of the surgically removed pancreas did not reveal any tumors. Microscopically, the pancreas exhibited diffuse islet cell hyperplasia without nesidioblastosis. The patient remains euglycemic and has tolerated 24-hour fasting without any medication for a period of 10 months after the operation.

Partial pancreatectomy was performed in a female patient with islet cell nodular hyperplasia, who repeatedly suffered from hypokalemia and hypoglycemia without diarrhea.After surgical operation,her symptoms were relieved.
