The typical sonogram of polycystic liver and polycystic kidney can be clearly diagnosed mainly by ultrasound examination. The typical sonogram of polycystic liver shows diffuse enlargement of the liver with uneven surface peritoneum and abnormal morphology, and round or round-like echogenic areas of variable size and clear borders are seen in the liver parenchyma, and there is no abnormal blood flow signal around these echogenic areas. Polycystic liver and kidney are benign lesions of the body, and usually do not require treatment when they are small in diameter, without secondary infection or compression symptoms.
