Discussion (Related Text)
Choledochal cysts are uncommon congenital anomalies of the biliary tree characterized by cystic dilation of the bile ducts . Many (60%) present in infancy or childhood, while others present in adulthood. Some are discovered by fetal US. The condition is much more common in females (70% to 84% of cases). Patients present with abdominal pain, mass, and jaundice. The Todani classification (1977) is typically used to describe choledochal cysts . Type 1 lesions are most common (80% to 90%) and appear as fusiform or saccular dilatations of the CHD, CBD, or segments of each. Type 2 lesions are diverticula of the CBD attached by a narrow stalk. Type 3 lesions are termed choledochoceles and are focal dilatations of the intraduodenal portion of the CBD, closely resembling ureteroceles. Type IV lesions are defined as multiple focal dilatations of the IHBDs and EHBDs usually with a focal large cystic dilatation of the CBD. Type 5 lesions are referred to as Caroli disease, which is more properly classified as a disease separate from choledochal cyst.
