Abstract
BackgroundMucinous cyst neoplasm of the liver (MCN-L) comprise less than 5% of all cystic liver lesions and is characterized by the presence of ovarian stroma and absence of bile duct communication.Case presentationHere, we discuss a 45-year-old woman who presented with symptomatic liver mass. Diagnostic workup detected a 4.2 × 3.6 cm septate cyst located in segments I, V, and VIII of the liver in communication with the right hepatic duct. An open right liver resection with total bile duct excision and hilar lymphadenectomy was performed. Pathology revealed a multiloculated cyst with lined mucinous epithelium and ovarian-like stroma, consistent with low-grade MCN-L.ConclusionsThis case shows that unusual location and bile duct communication can be present in MCN-L.

World Health Organization (WHO) had classified the cystic neoplasm of the liver into mucinous cystic neoplasm of the liver (MCN-L) and intraductal papillary neoplasm of the bile duct (IPN-B), similar to the classification used in pancreas [1]
Summary
Mucinous cyst neoplasm of the liver (MCN-L) comprise less than 5% of all cystic liver lesions and is characterized by the presence of ovarian stroma and absence of bile duct communication.Case presentation: Here, we discuss a 45-year-old woman who presented with symptomatic liver mass. Conclusions: This case shows that unusual location and bile duct communication can be present in MCN-L. MCN-L comprise less than 5% of all cystic liver diseases and is characterized by the presence of ovarian stroma and absence of bile duct communication.
