一名 58 岁男性，有吞咽困难和牙关紧闭症状，体检时发现右侧扁桃体有分叶状肿瘤，同侧颈椎后侧石性腺病。他患有前列腺癌作为临床先例。扁桃体病变在 PET/CT 上显示局灶性 FDG 摄取（SUVmax，10.89），左骶翼血糖代谢增加（SUVmax，10.90），但 CT 上没有明显的形态学病变。骨扫描中骶骨也吸收了示踪剂。怀疑有转移，需要进行放射引导活检以确定病因。通过放射引导活检，对转移进行了组织学分析，并诊断了表皮样癌转移。版权所有 © 2024 Wolters Kluwer Health, Inc. 保留所有权利。

A 58-year-old man with dysphagia and trismus symptoms presented a lobulated tumor in the right tonsil and ipsilateral laterocervical stony adenopathies in the physical examination. He had prostate carcinoma as clinical precedent. The tonsilar lesion showed focal FDG uptake (SUVmax, 10.89) on PET/CT and increased glycemic metabolism in the left sacral wing (SUVmax, 10.90) without clear morphological lesion in CT. There was also uptake of the tracer in sacrum in the bone scan. Metastatic involvement was suspected, requiring radioguided biopsy to determine the etiology. Due to radioguided biopsy, histological analysis of the metastasis was performed, with epidermoid carcinoma metastasis diagnosis.Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.
