We present a case of a 69-year-old man with primary hepatic carcinosarcoma who underwent computed tomography that revealed a hypervascular hepatic tumor with local dense calcification. Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging revealed hyperintense lesions in the hepatobiliary phase that indicated hepatocellular carcinoma with bile production. The patient underwent right lobectomy, and the presence of a sarcoma component within the tumor on histopathology confirmed liver carcinosarcoma that included hepatocellular carcinoma. In cases with atypical images that resemble this case, the hyperintensity of a lesion in the hepatobiliary phase aids differential diagnosis.
我们报告一例69岁原发性肝肉瘤样癌男性患者，其计算机断层扫描显示肝脏有一个强化血管性肿瘤伴局部致密钙化。钆塞酸二钠（Gd-EOB-DTPA）增强磁共振成像显示肝胆期高信号病变，提示有胆汁生成的肝细胞癌。患者接受了右半肝切除术，组织病理学显示肿瘤内存在肉瘤成分，证实为包含肝细胞癌的肝肉瘤样癌。在具有类似该病例的非典型影像的病例中，肝胆期病变的高信号有助于鉴别诊断。
