Abstract

A 48-year-old woman, chronic hepatitis B virus carrier, was presented with a 3.2-cm hepatic tumor accidentally noted 1 month ago by regular sonography. Serum α-fetoprotein level was within reference range, and tumor biopsy showed lymphoepithelioma-like carcinoma. She was referred for F-FDG PET/CT for whole-body survey. FDG PET/CT revealed a 3.2-cm FDG PET/CT in S5 to S6 of the liver, as well as lymphadenopathy in the left supraclavicular fossa and between the inferior venous cava and the common bile duct. Lymphoepithelioma-like carcinoma in the liver is extremely rare, and the expression of FDG uptake has never been discussed.

摘要

一位 48 岁的女性，慢性乙型肝炎病毒携带者，1 个月前常规超声偶然发现 3.2cm 的肝肿瘤。血清甲胎蛋白水平在参考范围内，肿瘤活检显示淋巴上皮样癌。她因全身 F-FDG PET/CT 检查而被转介。FDG PET/CT 显示 S5 到 S6 段肝脏有 3.2cm 的 FDG PET/CT，以及左锁骨上窝和下腔静脉与胆总管之间的淋巴结病。肝淋巴上皮样癌极为罕见，FDG 摄取的表达从未被讨论过。
