Pancreatic Insulinoma Presenting with Episodes of Hypoinsulinemic Hypoglycemia in Elderly-A Case Report
以低血糖低胰島素血症爲表現的胰島細胞腫瘤－病例報告
摘要
我們報告一個罕見病例，一位有胰島細胞腫瘤的老年人，實驗室檢驗診斷爲低血糖低胰島素血症。胰島細胞腫瘤的臨床表現特點爲反覆自發性的空腹低血糖，而診斷上是依據發生低血糖時同時有不正常偏高的胰島素值或是偏高的胰島素對血糖的比值。這篇報告說明單依靠低血糖低胰島素血症不能絕對排除胰島細胞腫瘤的診斷可能性。在高度懷疑罹患胰島細胞腫瘤的病人，卻出現低血糖低胰島素血症，當其低血糖時，除了測定血中胰島素濃度之外，應考慮進一步分析測定有交互反應的胰島素或前胰島素或類胰島素生長因子濃度。

We report a rare case of pancreatic islet cell tumor (insulinoma) presenting with hypoinsulinemic hypoglycemia in an elderly man by laboratory diagnosis. Insulinoma is characterized by spontaneous fasting hypoglycemia and its diagnosis relies on inappropriately increased insulin levels during episode of hypoglycemia and/or high insulin/glucose ratio. This report highlighted that the diagnosis of insulinoma or islet cell tumor cannot be excluded by hypoinsulinemic hypoglycemia absolutely. Further analytic measurements for cross-reacting insulin or determination of proinsulin or insulin-like growth factor levels should be considered when highly suspected insulinoma or documented pancreatic nodule was found in patients with hypoglycemic episode.
