Hepatoid adenocarcinoma is a rare extrahepatic tumor that shows clinicopathologic and morphologic similarities to hepatocellular carcinoma. An FDG PET/CT imaging of primary mediastinal hepatoid adenocarcinoma in a 43-year-old man who had an elevated serum alpha-fetoprotein level was reported in this case. The patient's mediastinal lesion had avid FDG uptake. Hepatoid adenocarcinoma should be considered among the differential diagnoses when an FDG-avid extrahepatic mass is seen in patients with increased alpha-fetoprotein.
肝样腺癌是一种罕见的肝外肿瘤，在临床病理和形态学上与肝细胞癌相似。本文报道了一例43岁血清甲胎蛋白水平升高的原发性纵隔肝样腺癌患者的FDG PET/CT影像。患者纵隔病变有明显的FDG摄取。当甲胎蛋白升高的患者出现FDG摄取阳性的肝外肿块时，鉴别诊断应考虑肝样腺癌。
