In 2010, the World Health Organization classified mucin-producing bile duct tumors of the liver into two distinct entities; mucinous cystic neoplasm of the liver (MCN-L) and intraductal papillary mucinous neoplasm of the bile duct. We present the case of a patient with MCN-L having a uniquely pedunculated shape. A 32-year-old woman was referred to our institution with a diagnosis of biliary cystic neoplasm. She had undergone left salpingo-oophorectomy for ovarian cancer 15 years ago. Imaging studies showed an 8 cm-sized well defined, multiloculated cystic lesion suggesting a mucinous cystic neoplasm. The cystic mass was pedunculated at the liver capsule and pathologically diagnosed as MCN-L. The mass was resected with partial hepatectomy. The patient recovered uneventfully. She was discharged 7 days postoperatively. The patient has been doing well for 6 months after the operation. The patient will be followed up annually because of the favorable postresection prognosis of MCN-L.
2010年，世界卫生组织将肝脏产生黏液的胆管肿瘤分为两个不同的实体：肝脏黏液性囊性肿瘤（MCN-L）和胆管内乳头状黏液性肿瘤。我们报告了一例具有独特带蒂形状的MCN-L患者。一名32岁女性因诊断为胆管囊性肿瘤转诊至我院。她15年前因卵巢癌接受了左侧输卵管卵巢切除术。影像学检查显示一个8厘米大小、边界清晰的多房囊性病变，提示为黏液性囊性肿瘤。囊性肿块在肝包膜处有蒂，病理诊断为MCN-L。通过部分肝切除术切除肿块。患者恢复顺利。术后7天出院。术后6个月患者情况良好。由于MCN-L切除术后预后良好，患者将每年接受随访。
