Hepatic cystic foci is an imaging description of a cystic, space-occupying lesion found in the liver, which is usually surrounded by a cystic wall at its periphery, and the lesion is confined. Hepatic cystic foci are usually hepatic cysts, which usually appear as hypodense shadows on CT and hypoechoic or echogenic areas on ultrasound. The foci are usually well defined with smooth margins. Most hepatic cysts are benign lesions and usually have no obvious symptoms. If the cyst increases rapidly, it may cause abdominal mass, right abdominal pain, nausea and vomiting and other symptoms. To summarize, if cystic lesions appear in the liver, you should go to the hospital in time and be diagnosed and treated under the guidance of professional physicians.
