Mucinous cystic neoplasms of the liver: Literature review and case series

Table 1 Radiological criteria for mucinous cystic neoplasms of the liver

Criterion	Diagnostic importance
Multiloculated cystic lesion	Common feature of MCN-L
Septations	If > 3 mm, considered a major feature for high suspicion
Internal nodules	Major feature for high suspicion
Calcifications	Present in 47%-63% of cases
Thickened, irregular cyst walls	Common feature of MCN-L
Mural nodules with enhancement	Highly suggestive of MCN-L
Predilection for the left hepatic lobe (segment IV)	Found in 69%-76% of cases
Biliary duct dilatation	Minor feature
Absence of communication with bile ducts	Helps differentiate from IPNB
Echogenic septations (on ultrasound)	Key ultrasonographic feature
Contrast enhancement (on MRI)	Highly sensitive feature on MRI

MCN-L: Mucinous cystic neoplasms of the liver; MRI: Magnetic resonance imaging; IPNB: Intraductal papillary neoplasm of the bile duct.
