Localization of insulinomas by preoperative imaging is critical for successful surgical resection. However, the visualization and localization of small insulinomas by recent imaging modalities still remains a challenge. Here, we report a 77-year-old woman with a small insulinoma successfully localized by performing arterial stimulation and venous sampling (ASVS), and subsequent super-selective CTA (SSCTA). It was not visualized by routine non-invasive imaging tests such as digital subtraction angiography (DSA). The small size (1.0 cm) of the surgically removed tumor supports the usefulness of SSCTA for localizing very small insulinomas.
术前影像学检查对胰岛素瘤进行定位对于成功实施手术切除至关重要。然而，采用近期的影像学检查方法对小胰岛素瘤进行可视化和定位仍然是一项挑战。在此，我们报告一名77岁女性，其小胰岛素瘤通过动脉刺激和静脉采血（ASVS）以及随后的超选择性CT血管造影（SSCTA）成功实现了定位。常规非侵入性成像检查如数字减影血管造影（DSA）未能显示该肿瘤。手术切除肿瘤的小尺寸（1.0厘米）证实了SSCTA对定位极小胰岛素瘤的有效性。
