Figure 6 A 34-year-old female patient. Liver magnetic resonance imaging demonstrated a multiloculated cystic mass in S4b, hypointense on T1 sequences with isointense septa, hyperintense on T2 sequences, slightly hyperintense on diffusion weighted images and without significant restriction on the ADC map. On dynamic study after gadoxetic acid administration, the lesion presents no enhancement even in the septal components. On the hepatobiliary excretion phase the mass is hypointense. After surgical resection, histological examination demonstrated a biliary cystadenoma.
