Abstract

Abstract: 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.

肝实质周围 HCC 的 TACE 后 FDG 累积：区分炎性假瘤和 HCC。

摘要：一名80岁的肝细胞癌（HCC）患者接受了18 F-FDG PET/CT扫描，原因是2周前在经动脉化疗栓塞（TACE）期间通过CT扫描发现了疑似腰椎转移灶。正电子发射计算机断层扫描显示，HCC 及其周围的肝实质存在节段性高摄取，TACE 期间沉积的脂碘醇大部分已被冲走。4个月后进行的18 F-FDG PET/CT随访扫描证实，HCC周围肝实质的摄取量降低了。这凸显了在TACE后18 F-FDG PET/CT评估中区分炎症和存活HCC的必要性。
