Hepatic Cysts

Approximately 30% of patients have hepatic cyst and in a minority of patients massive enlargement of the polycystic liver is seen.

Pain, infection of cysts and, more rarely, compression of the bile duct, portal vein or hepatic venous outflow may occur. Rarely, percutaneous drainage of painful cysts, laparoscopic fenestration or even partial hepatectomy may be necessary. Infected cysts may require drainage.

If the patient is asymtomatic and the liver enzymes are normal, a finding like this does not cause any need for further evaluation, and the prognosis is good. If a cyst produce symtom, it can be drained.

Hepatic cysts are are probably congenital, with an epithelial lining, and most often they do not give any symtoms and are most often found in ultrasound done for other reasons. Very seldom a large cyst can cause biliary compression and cholestasis.

Most often, expectant behaviour and no treatment is appropriate. For symptomatic cysts, different approaches have been described.

Percutaneous aspiration with ethanol sclerotherapy is a safe, effective, and minimally invasive treatment method for symptomatic congenital cysts. It is the initial treatment of choice for all patients with symptomatic congenital hepatic cysts.
