摘要

一名47岁男子在接受超声检查时被偶然诊断为肝脏肿瘤。动态CT和MRI显示4.8×3.7×3.5 cm病变，进行性外周增强，T2WI信号不均匀。18F-FDG PET/CT显示肿瘤中FDG摄取适度（SUVmax 4.7），无其他原发病变。经组织病理学诊断为原发性肝肌外皮细胞瘤，一种极为罕见的良性肿瘤，迄今文献报道仅有6例。本病例报告强调了临床和影像学特征，特别是18F-FDG PET/CT在鉴别肌外皮细胞瘤与肝转移、肝内胆管癌等肝恶性肿瘤中的作用。

A Case of Primary Hepatic Myopericytoma, Rare Benign Tumor, Depicted With 18 F-FDG PET/CT.

A 47-year-old man was incidentally diagnosed with a hepatic tumor while undergoing ultrasonography. Dynamic CT and MRI revealed a 4.8×3.7×3.5 cm lesion with progressive peripheral enhancement and heterogeneous T2WI signals. 18 F-FDG PET/CT demonstrated moderate FDG uptake (SUV max 4.7) in the tumor without other primary lesions. The patient was histopathologically diagnosed with primary hepatic myopericytoma, an extremely rare benign tumor, with only 6 cases reported in the literature to date. This case report highlights the clinical and imaging features, especially the role of 18 F-FDG PET/CT, in distinguishing myopericytoma from malignant hepatic tumors such as liver metastasis and intrahepatic cholangiocarcinoma.
