Choledochal Cysts in Adults: A Case Report and Literature Review.

Choledochal cysts are a rare malformation of the biliary tract with an unknown etiology, predominantly affecting Asians and females.

There are no pathognomonic clinical manifestations; the clinical presentation is associated with gallstones, choledocholithiasis, pancreatitis, cholangitis, and an increased risk of malignancy.
