Liver hyperechoicity with normal liver function may be the result of a liver lesion that is not severe enough to cause liver function changes, or just not present for the time being. A normal liver shows uniform and fine isoechoicity on ultrasound, and hyperechoicity can be seen when the liver is diseased. Hypoechoicity in the liver can be seen in a variety of possible conditions, such as liver abscess, liver cysts, fatty liver, and various types of hepatitis and liver injury. When hyperecho is found in the liver, it needs to be taken seriously and the relevant examinations should be improved to clarify the cause of the disease. If hypoechoicity is found in the liver, but the liver function test indicators are normal, it may be that the localized lesions in the liver are mild and the liver has compensatory function, so it has not yet caused changes in the clinical indicators. Ultrasound examination or further CT examination can be repeated.
