Scanning for somatostatin receptors using ⁶⁸Ga-dotatate positron emission tomography with co-registration with computed tomography or magnetic resonance imaging is now in widespread use for the identification of neuroendocrine tumours, phaeochromocytomas, and paragangliomas and their metastases. We present a case where a patient with a phaeochromocytoma showed uptake in her neck considered diagnostic of a head-and-neck paraganglioma, which was subsequently confirmed to be a metastatic papillary thyroid carcinoma. We alert clinicians to such falsely-identified tumours using this extensively used imaging technique.

对有嗜铬细胞瘤病史的患者进行 68 点状镓 PET 扫描具有误导性：甲状腺乳头状癌转移中意外的摄取

使用⁶⁸ Ga 正电子发射断层扫描扫描生长抑素受体，并与计算机断层扫描或磁共振成像联合配准，现已广泛用于识别神经内分泌肿瘤、嗜铬细胞瘤、副神经节瘤及其转移瘤。我们介绍了一个病例，一名嗜铬细胞瘤患者的颈部出现摄取，被认为是头颈副神经节瘤的诊断，随后被证实为转移性甲状腺乳头状癌。我们使用这种广泛使用的成像技术提醒临床医生注意此类错误识别的肿瘤。
