摘要：
一名 80 岁肝细胞癌 (HCC) 患者因 2 周前经动脉化疗栓塞 (TACE) 期间进行的 CT 扫描发现疑似腰椎转移，接受了 18 F-FDG PET/CT 扫描。 PET 扫描显示 HCC 和周围肝实质中存在节段性高摄取，TACE 期间沉积的碘油大部分已被洗掉。节段性摄取归因于 TACE 诱导 HCC 周围肝实质的炎症变化，4 个月后的后续 18 F-FDG PET/CT 扫描中摄取减少证实了这一点。这凸显了在 TACE 18 F-FDG PET/CT 评估中区分炎症和活 HCC 的必要性。版权所有 © 2024 Wolters Kluwer Health, Inc. 保留所有权利。
An 80-year-old patient with hepatocellular carcinoma (HCC) underwent an 18 F-FDG PET/CT scan owing to suspected lumbar metastasis identified via a CT scan performed during transarterial chemoembolization (TACE) 2 weeks earlier. The PET scan revealed segmental high uptake in the HCC and surrounding liver parenchyma, where lipiodol deposited during TACE had mostly washed out. The segmental uptake was attributed to TACE-induced inflammatory changes in the liver parenchyma around the HCC, confirmed by reduced uptake in a follow-up 18 F-FDG PET/CT scan 4 months later. This highlights the need to differentiate between inflammation and viable HCC in post-TACE 18 F-FDG PET/CT evaluations.Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.
