[Echotomography in polycystic renal disease].

Sonography is a safe and suitable diagnostic tool; to date it appears to be the most valuable method for detecting renal cystic lesions. In particular ultrasound examination, if a wider district is screened, can demonstrate the coexistence of the cystic disease in different organs. The Authors report a case of renal polycyctic disease in which the sonographic examination was extended to the entire abdomen disclosing simultaneous involvement of the kidneys and the liver.
