We report on a middle-aged woman who presented with clinical and biochemical findings of insulinoma. Preoperative evaluation by ultrasound, CT, and angiography located the pancreatic lesion but also revealed two focal liver lesions. The latter were interpreted as metastases. MR imaging with injection of superparamagnetic iron oxide particles not only localized the insulinoma but proved to be the only noninvasive technique capable to exclude presence of liver metastases preoperatively. This reversed management to minimal laparoscopic surgery. Recent literature of preoperative imaging evaluation of insulinoma and focal liver lesions is discussed.
我们报告了一名患有胰岛素瘤的中年女性，其具有胰岛素瘤的临床和生化表现。术前通过超声、CT和血管造影进行评估，确定了胰腺病变，但也发现了两个肝脏局灶性病变。后者被认为是转移灶。注射超顺磁性氧化铁颗粒的磁共振成像不仅定位了胰岛素瘤，而且被证明是术前唯一能够排除肝转移存在的非侵入性技术。这使得治疗方案转变为微创腹腔镜手术。本文还讨论了胰岛素瘤和肝脏局灶性病变术前影像学评估的近期文献。
