一位24岁的无症状女性，在胰腺棘突有外生性原始神经外胚层肿瘤病史，采用Tc-99m肼烟碱- tyr3 -奥曲肽（HYNIC-TOC）显像作为常规检查的一部分进行评估。图像显示胰腺头部局部活动增强，提示肿瘤可能复发。然而，考虑到所有检查的结果，特别是由于解剖成像的阴性结果，HYNIC-TOC扫描的发现被认为可能是假阳性，因此没有采取新的措施。18个月后，患者腹部出现肿块。重复hyic - toc显像再次显示异常活动病灶，病理证实为复发性原始神经外胚层肿瘤。
A 24-year-old asymptomatic female with a history of exophytic primitive neuroectodermal tumor in the uncinate process of the pancreas was evaluated by Tc-99m hydrazinonicotinyl-Tyr3-octreotide (HYNIC-TOC) imaging as a part of the routine check-up. The images revealed focally increased activity in the head of the pancreas, indicating possible recurrent tumor. However, the results of all examinations considered, especially because of negative results from anatomic imaging, the finding from the HYNIC-TOC scan was regarded as likely false positive, and no new actions were taken. Eighteen months later, the patient developed abdominal mass. Repeat HYNIC-TOC imaging redemonstrated the focus of abnormal activity, which was confirmed as recurrent primitive neuroectodermal tumor pathologically.
