Abstract：
Primary clear cell carcinoma of liver (PCCCL) is a special and relatively rare subtype of hepatocellular carcinoma (HCC), which is more common in people over 50 years of age, with a preference for men and a history of hepatitis B or C and/or cirrhosis. Herein, we present a case of a 60-year-old woman who came to our hospital for medical help with right upper abdominal pain. The imaging examination showed a low-density mass in the right lobe of his liver. In contrast enhanced computed tomography (CT) or T1-weighted imaging, significant enhancement can appear around the tumor during the arterial phase, and over time, the degree of enhancement of the tumor gradually decreases. The lession showed obviously increased fluorine-18 fluorodeoxyglucose (18F-FDG) uptake on positron emission tomography/CT. These imaging findings contribute to the diagnosis of PCCCL and differentiate it from other types of liver tumors.
摘要：
原发性透明细胞肝癌（PCCCL）是肝细胞癌（HCC）的一种特殊且相对罕见的亚型，这在50岁以上的人中更常见，偏爱男性，有乙型肝炎或丙型肝炎和/或肝硬化病史。在这里，我们介绍了一个60岁的妇女，她来我们医院寻求右上腹痛的医疗帮助。影像学检查显示他的肝脏右叶有低密度肿块。在对比增强计算机断层扫描（CT）或T1加权成像中，在动脉期肿瘤周围可以出现明显的增强，随着时间的推移,肿瘤的增强程度逐渐降低。在正电子发射断层扫描/CT上显示氟18氟脱氧葡萄糖（18F-FDG）的摄取明显增加。这些影像学发现有助于PCCCL的诊断并将其与其他类型的肝肿瘤区分开。
