Abstract

We report a case of hepatocellular carcinoma (HCC) with multiple lymph node (LN) metastases. A 68-year-old man underwent hepatectomy at our hospital. Intrahepatic recurrence and swelling of multiple LNs were detected by enhanced CT 21 months later. FDG-PET was positive for multiple swollen LNs, but all were negative for the intrahepatic recurrences. Biopsy of para-aortic LNs was revealed LN metastases from HCC. Immunohistochemically, the LN metastases were composed of poorly differentiated HCC. The sensitivity of FDG-PET in patients with HCC varies in relation to degree of differentiation and decreased FDG uptake must be noted.

ferorine -18-fluorodeoxyglucose positron emission tomography (FDG-PET)显示异常高聚集的肝细胞癌多发淋巴结转移1例
我们报告一例肝细胞癌伴多发淋巴结转移的病例。一位68岁男性在我院行肝切除术。21个月后增强CT检查肝内多发淋巴结肿大及复发。FDG-PET对多发肿大的LNs呈阳性,但对肝内复发均呈阴性。主动脉旁淋巴结活检显示肝细胞癌淋巴结转移。免疫组织化学分析,淋巴结转移由低分化HCC组成。肝癌患者FDG- pet的敏感性随分化程度的不同而不同,必须注意FDG摄取减少。
