Abstract

BACKGROUND

Tumor-associated hypoglycemia can be caused by non-islet cell tumors including gastrointestinal stromal tumor (GIST) which is a rare paraneoplastic syndrome that leads to the release of insulin-like growth factor-2 (IGF-2).

CASE PRESENTATION

We report the case of a 45-year old woman who was admitted to our hospital with refractory hypoglycemic episodes. We found normal serum insulin and c-peptide level and abdominal CT-scan showed a small duodenal wall lesion suggesting insulinoma. After tumor resection, hypoglycemia symptoms were recovered, but the pathological findings demonstrated the lesion was GIST.

CONCLUSION

In a small gastrointestinal lesion with hypoglycemic symptoms we should consider IGF-II secreting GIST in addition to insulinoma.

摘要

背景

肿瘤相关性低血糖可由非胰岛细胞瘤引起，包括胃肠道间质瘤（GIST），这是一种罕见的副肿瘤综合征，可导致胰岛素样生长因子-2（IGF-2）的释放。

病例报告

我们报告了一名45岁女性的病例，她因难治性低血糖发作入院。我们发现血清胰岛素和C肽水平正常，腹部CT扫描显示十二指肠壁有一个小病变，提示胰岛素瘤。肿瘤切除后，低血糖症状得以恢复，但病理结果显示该病变为胃肠道间质瘤。

结论

对于有低血糖症状的小胃肠道病变，除了胰岛素瘤外，我们还应考虑分泌IGF-II的胃肠道间质瘤。
