A 70-year-old man with a liver tumor was pathologically diagnosed with multicystic biliary hamartoma with xanthogranulomatous inflammation. Plain CT revealed an inhomogeneous low-density liver tumor, measuring 43 × 35 mm. Dynamic contrast-enhanced CT revealed a cyst, measuring approximately 15 mm, with a ring-shaped enhancement, within the tumor. There was delayed enhancement on the outer portion of the tumor. Mild peripheral bile duct dilation was also observed. 18F-FDG PET/CT showed focal high uptake with an SUVmax of 5.2 near the cyst. The findings of this case mimicked that of intrahepatic cholangiocellular carcinoma.
一位 70 岁男性，因肝脏肿瘤行病理检查诊断为多房性胆管先天性畸形伴黄色肉芽肿性炎症。平扫 CT 显示肝脏混杂密度肿瘤，大小约 43×35mm。动态增强 CT 显示肿瘤内约 15mm 的囊性病灶，呈环形强化，肿瘤外周呈延迟强化。同时伴有轻度肝外胆管扩张。18F-FDG PET/CT 显示病灶周边局灶性高摄取，SUVmax 约为 5.2。该病例的影像学表现类似于肝内胆管细胞癌。
