To retrospectively analyse the different imaging manifestations of acquired immunodeficiency syndrome-associated hepatic Kaposi's sarcoma (AIDS-HKS) on CT, MRI, and Ultrasound.
Eight patients were enrolled in the study. Laboratory tests of liver function were performed. The CT, MRI, and Ultrasound manifestations were reviewed by two radiologists and two sonographers, respectively. The distribution and imaging signs of AIDS-HKS were evaluated.
AIDS-HKS patients commonly presented multiple lesions, mainly distributed around the portal vein on CT, MRI, and Ultrasound. AIDS-HKS presented as ring enhancement in the arterial phase on contrast-enhanced CT and MRI scanning, and nodules gradually strengthen in the portal venous phase and the delayed phase. AIDS-HKS presented as intrahepatic bile duct dilatation and bile duct wall thickening around the lesion. Five patients (62.5%, 5/8) were followed up. After chemotherapy, the lesions were completely relieved (60.0%), or decreased (40.0%).
AIDS-HKS presented as multiple nodular lesions with different imaging features. The combination of different imaging methods was helpful for the imaging diagnosis of AIDS-HKS.
回顾性分析获得性免疫缺陷综合征相关肝卡波西肉瘤（AIDS-HKS）在CT、MRI及超声上的不同影像表现。
纳入8例患者进行研究。进行肝功能实验室检查。由两名放射科医生和两名超声科医生分别回顾CT、MRI及超声表现。评估AIDS-HKS的分布及影像征象。
AIDS-HKS患者通常表现为多发病变，主要分布于CT、MRI及超声上的门静脉周围。在CT和MRI增强扫描的动脉期，AIDS-HKS表现为环形强化，在门静脉期和延迟期结节逐渐强化。AIDS-HKS表现为肝内胆管扩张及病变周围胆管壁增厚。对5例患者（62.5%，5/8）进行随访。化疗后，病变完全缓解（60.0%）或缩小（40.0%）。
AIDS-HKS表现为具有不同影像特征的多发结节性病变。不同影像方法的联合有助于AIDS-HKS的影像诊断。
