放射影像(一一六)肝臟黏液囊性腫瘤與膽管導管內乳頭狀瘤

摘要


肝臟黏液囊性腫瘤(mucinous cystic neoplasm of the liver)和膽管內乳頭狀腫瘤(intraductal papillary neoplasm of the bile duct)為兩種罕見且不同種類之腫瘤,各具有獨特的臨床、病理和影像學特徵、治療方式和預後,MCN的關鍵病理特徵為上皮下類卵巢基質(subepithelial ovarian-likes troma),在2010年世界衛生組織(WHO)提出前述病理特徵之前,兩種腫瘤的分類仍不明且具爭議。大多數肝臟黏液囊性腫瘤為良性,而膽管內乳頭狀腫瘤通常與浸潤性癌有關。在影像上,膽管溝通、管內腫塊和相關的膽管擴張是區分IPNB與MCN和其他肝臟囊性腫塊的關鍵。本文針對上述兩種腫瘤之最新命名、病理和影像學特徵(本院案例)、治療方式及預後提供概略簡介。
