9.4 Isolated biliary cysts
Presents as frequent incidental finding in the liver.
Solitary liver cysts are very common and are usually found incidentally on imaging. A distinction must be made with PCLD, in which by definition more than twenty cysts are present. Solitary biliary cysts do not cause symptoms. Consequently, atypical upper abdominal complaints cannot be attributed to an incidentally found liver cyst. Large cysts can sometimes compress the surrounding organs due to their volume. This results in a rapid feeling of satiety. Very rarely, such a cyst can become infected.
The diagnosis is made by ultrasound, or a CT or MRI scan. A distinction must be made between a cystadenoma and cystadenocarcinoma (very rare). Percutaneous or CT-guided puncture aspiration usually gives very rapid recurrence, unless alcoholization occurs. Very rarely surgery is necessary, in which a marsupialation or fenestration is performed.
Isolated biliary cysts
Choledochal cysts (CC) are rare medical conditions and consist of cystic dilatations of the extrahepatic biliary tree, intrahepatic biliary ducts or both, with anincidence in the western population of 1 in 100,000-150,000 live births, although the incidence has been reported to be as high as 1 in 13,500 births in the United States and 1 in 15,000 births in Australia. The rate is remarkably higher in Asian populations with a reported incidence of 1 in 1000, and about two thirds of cases occur in Japan. The reason for this Asian preponderance is still unclear. There is also an unexplained female:male preponderance, commonly reported as 4:1 or 3:1.2. CC are classified into five main types with several subtypes. Anatomical configurations, which do not readily fall into the Todani modification, have been described.
