Liver cysts in patients with autosomal dominant polycystic kidney disease

Abstract

Liver cysts were found in 46 (29 per cent) of 158 patients over 10 years of age with documented autosomal dominant-type polycystic kidney disease (PKD) from 62 unrelated families. Hepatic cysts were not found in any patient at risk for PKD in whom renal cysts were not detected. The prevalence of liver cysts increased with advancing age and with declining rate of glomerular filtration. Results of clinical and laboratory studies indicate that polycystic liver disease in patients with autosomal dominant-type PKD is a benign condition, rarely, if ever, causing impaired liver function or portal hypertension.
