Overview

Biliary cystadenoma is a rare disease. The median age at diagnosis of biliary cystadenoma is 45 years. Females are more commonly affected with biliary cystadenoma than males.

Epidemiology and Demographics

Biliary cystadenomas constitute less than 5% of cystic lesions of the liver.^[1] Biliary cystadenoma presents as an intrahepatic lesion in 90% of cases, while in the remaining cases it involves the extrahepatic biliary tree.^[2]

Age

The majority of patients are middle-aged women with an average age of 45 at time of diagnosis.^[3]
The peak frequency has been reported between the fourth and the sixth decades.^[2]
However, in a few cases, cystadenomas have been observed in the second decade of life.

Gender

The majority of biliary cystadenomas occur in women (80-85%), and this suggested a role for hormonal influence.^[2]
