Biliary cystadenocarcinoma is a very rare malignant cystic tumor of the liver, which is often misdiagnosed due to a poor recognition of it. We report a case of a 60-year-old man with biliary cystadenocarcinoma with his real time contrast enhanced ultrasound (CEUS) characteristics compared to those of computed tomography (CT) and magnetic resonance imaging (MRI), which were correlated with the surgical and pathologic findings. Cystic wall enhancement, internal septations and intra-cystic solid portions in the arterial phase were observed on CEUS after contrast agent injection. The enhancement was washed out progressively and depicted as hypo-enhancement in the portal and late phases. CT revealed a large irregular cystic lesion in the left liver lobe with no clear septations and solid components. MRI showed an irregular cystic occupying lesion with septations.
胆管囊腺癌是一种非常罕见的肝脏恶性囊性肿瘤，由于对其认识不足，常被误诊。我们报告了一例 60 岁男性胆管囊腺癌患者，对其实时超声造影（CEUS）特征与计算机断层扫描（CT）和磁共振成像（MRI）进行了比较，并与手术和病理结果相关联。造影剂注射后，CEUS 观察到囊性壁增强、动脉期内分隔和囊内实性部分。增强逐渐洗脱，在门静脉期和晚期表现为低增强。CT 显示左肝叶有一个大的不规则囊性病变，无明显分隔和实性成分。MRI 显示不规则囊性占位病变伴分隔。
