Mucinous cystic neoplasm of the liver (MCN-L) is a rare epithelial tumor with ovarian-like stroma (OLS), accounting for less than 5% of hepatic cysts. While usually confined to the liver, MCN-L rarely invades the biliary tract, complicating diagnosis and treatment. This case report describes a 53-year-old woman with recurrent cholangitis after robotic hepatic resection for MCN-L. Imaging revealed a lesion in the bile ducts, initially suspected to be intraductal papillary neoplasm of the bile duct (IPNB). Robotic left hepatectomy using the Da Vinci platform was performed, and intraoperative findings confirmed an intraductal pedunculated mass. Histopathology identified MCN-L with OLS invading the biliary tract. The patient recovered uneventfully and was discharged on postoperative day two. Although rare, MCN-L with biliary invasion can mimic IPNB. Robotic surgery provides a minimally invasive solution, emphasizing the importance of early detection and intervention for optimal outcomes.
肝脏黏液性囊性肿瘤（MCN-L）是一种罕见的具有卵巢样间质（OLS）的上皮性肿瘤，占肝囊肿的比例不到5%。虽然MCN-L通常局限于肝脏，但很少侵犯胆道，这使得诊断和治疗变得复杂。本病例报告描述了一名53岁女性，在接受机器人肝脏切除术后因MCN-L出现复发性胆管炎。影像学检查发现胆管内有一个病变，最初怀疑是胆管内乳头状肿瘤（IPNB）。使用达芬奇平台进行了机器人左肝切除术，术中发现证实为胆管内带蒂肿块。组织病理学检查确定为MCN-L伴OLS侵犯胆道。患者恢复顺利，术后第二天出院。虽然罕见，但伴有胆道侵犯的MCN-L可能会模仿IPNB。机器人手术提供了一种微创解决方案，强调了早期检测和干预对于获得最佳结果的重要性。
