본 저자들은 44세의 여자환자로 3년전부터 발생한 경련성 발작후 의식소실로 간질로 진단 받은 후 항경련제를 투여받았으나 효과가 없었던, 금식검사에서 혈청 insulin, C-peptide, glucose, 24시간 뇨 c-peptide 및 선택적 췌장동맥 촬영술로 인술린종을 진단, 수술로 종물을 적출후 경련성 발작이 사라진 인술린종 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.
Insulinoma is a rare tumor, occurring more often in women and in the older age range. Eighty percent of patients have a single benign tumor, usually 2cm in diameter, located with about equal frequency in body, head or tail of pancreas and amenable to surgical cure. About 10% have multiple tumors. The remaining 10% of patients have metastatic malignant insulinoma. The symptom of insulinoma is characterized by the periodic attack of hypoglycemia of blood sugar level below 50mg%, by fasting or exertion, and rapid relief of symptom by oral or intravenous administration of glucose. Symptom often lead to misdiagnosis as a neurologic or psychiatric disorder. A case described by authors was 44-year old female with the chief complaints of the loss of consciousness, epileptic seizure although she has been treated by anticonvulsants. Serum blood sugar and insulin level during fasting sugested insulinoma but abdominal computed tomography shows no definitive mass in pancreas. Celiac angiography revealed insulinoma. She transfered to the defartment of General Surgery and was performed enucleation. Microscopic findings shows the islet cell tumor of pancreas. A brief review of the literature was made.
