摘要：
异位甲状腺组织罕见且通常位于甲状舌管或颈侧区域。我们报道了一名28岁女性患者的18F-FDG和68Ga-FAPI检查结果，该患者先前被诊断为具有未知原发灶的BRAF突变的颈侧淋巴结转移。在颏下气管前结节病灶中观察到18F-FDG低摄取但68Ga-FAPI摄取增加。术后病理报告证实了异位乳头状甲状腺癌的诊断。肿瘤样本中的FAP高表达与其影像表现相对应。版权所有 © 2023 Wolters Kluwer Health，Inc. 保留所有权利。
Ectopic thyroid tissue is rare and generally occurs along the thyroglossal duct or in lateral cervical region. We reported 18F-FDG and 68Ga-FAPI findings of a 28-year-old woman with previously diagnosed BRAF-mutated lateral lymph node metastasis of unknown primary site. Low 18F-FDG but increased 68Ga-FAPI uptake was seen in a submental pretracheal nodular lesion. Postsurgical pathologic report verified the diagnosis of ectopic papillary thyroid carcinoma. High FAP expression in the tumor sample corresponded to its imaging manifestations.Copyright © 2023 Wolters Kluwer Health, Inc. All rights reserved.
