Normal shape and size, intact envelope, fine echogenicity of liver parenchyma, two hypoechoic clusters visible in the left lobe of the liver indicate the presence of hepatic cysts, hemangiomas, liver tumors, etc., which need to be analyzed specifically. 1. Liver cyst: it is caused by congenital, traumatic or infectious factors, which makes the cystic cavity appear in the liver, most patients have no obvious symptoms, and some of them have abdominal pain, abdominal distension, jaundice and other symptoms. 2. Hemangioma: it is caused by developmental abnormality and other reasons, and the blood vessels in the liver are abnormally prominent, which is manifested as intact periphery and hypoechoic mass. 3.

If abnormal liver changes occur, it is recommended to go to the hospital in time and take reasonable methods of treatment under the guidance of the doctor to promote the alleviation of the condition.
