In this report, we present a 57-year-old female with a history of mild alcoholic liver disease during a medical check-up. Abdominal computed tomography and magnetic resonance imaging showed a multicystic mass with a solid enhancing mural nodule in the right lobe of the liver. Subsequently, laparoscopic right liver lobectomy was performed and pathological findings revealed intraductal papillary neoplasm of the bile duct (IPNB) with an associated invasive carcinoma. IPNB is a relatively rare disease that should be considered in the differential diagnosis of hepatic cystic tumours. Our case report highlights the importance of capturing image findings of the IPNB as this disease has a high potential for malignancy.
在本报告中，我们介绍了一名57岁女性，她在体检时被发现有轻度酒精性肝病病史。腹部计算机断层扫描和磁共振成像显示肝脏右叶有一个多囊性肿块，伴有一个实性强化的壁结节。随后，进行了腹腔镜右肝叶切除术，病理结果显示为胆管内乳头状瘤（IPNB）伴浸润性癌。IPNB是一种相对罕见的疾病，在肝囊性肿瘤的鉴别诊断中应予以考虑。我们的病例报告强调了捕捉IPNB影像表现的重要性，因为这种疾病具有很高的恶性潜能。
