DefinitionThis section has been translated automatically.

Liquid-filled cavity (cyst) embedded in the parenchyma of the liver, solitary or multiply occurring. Liver cysts are often found by chance in patients without symptoms and usually have no disease value. Liver cysts can be a partial symptom of "Autosomal dominant polycystic nephropathy".

Occurrence/EpidemiologyThis section has been translated automatically.

Solitary liver cysts occur in 3-5% of people > 50 years of age.

EtiopathogenesisThis section has been translated automatically.

The non-parasitic cysts may be hereditary (congenital), traumatic (due to external action) or neoplastic (new formation).

Liver cysts may also form as a result of intrahepatic bile duct obstruction.

Extremely rarely, liver cysts form as a degenerative concomitant of liver cirrhosis.

In autosomal dominant polycystic nephropathy (ADPKD - Q61.2), liver cysts are encountered in nearly 100% of cases; they are combined with pancreatic cysts and cerebral base artery aneurysms in 10% of cases.

Clinical featuresThis section has been translated automatically.

Liver cysts have a roundish shape that is sharply delineated from the rest of the tissue and has a delicate wall. They generally enlarge very slowly.

ImagingThis section has been translated automatically.

Sonography: round, echo-free, smoothly limited structure with distal sound amplification.

Differential diagnosisThis section has been translated automatically.

Parasitic (e.g. Echinococcus granulosus) cystic echinococcosis.

Complication(s)This section has been translated automatically.

Rarely bleeding or infection

Operative therapieThis section has been translated automatically.

A surgical indication is only given in the case of corresponding pain problems, very large cysts or so-called cyst livers (due to multiple cysts, the liver can have a significantly increased volume). The symptomatic cysts are opened laparoscopically and relieved. Alternatively, sclerotherapy of the cyst(s) can be performed under laparoscopic control (20% NACL solution; Polidocanol: Jusufovic R et al. 2011; Spârchez Z et al. 2014).

Note(s)This section has been translated automatically.

Similar to the kidney, the liver is also differentiated between a liver cyst and a cyst liver (liver parenchyma interspersed with numerous cysts like honeycombs).
