Slightly dense liver echoes may be associated with fatty liver, cirrhosis, and hepatic hemangioma. Slightly dense liver echogenicity is often a manifestation of hepatocyte membrane damage, which is common in the following diseases: 1. Fatty liver: it is an early manifestation of liver damage caused by various reasons. Ultrasonography can see that the liver parenchyma is microscopic and dense with strong reflective light spots and the deep tissue echoes are weakened. 2. Cirrhosis: it is a common chronic liver disease, which can be caused by one or more causes of liver damage, with progressive, diffuse and fibrous liver lesions. Ultrasonography shows that in early stage, hepatomegaly, dense echogenicity in liver parenchyma, enhanced echogenicity and coarsening can be seen; in late stage, the liver shrinks and the surface of the liver is uneven, often accompanied by ascites and other changes. 3. Hepatic hemangioma: it is the most common benign tumor in the liver, with hepatic cavernous hemangioma being the most common. Ultrasonography often shows single or multiple hyperechoic areas in the liver, or hyperechoic. The shape of the mass is regular, the border is clear, the internal echo is uniform, dense and sieve-like, and sometimes the surrounding small ducts can be seen directly into the lesion, presenting the “marginal fissure sign”. Slightly dense liver echoes can not accurately determine the disease, but also need to be combined with the characteristics of the medical history, other test results to make an accurate judgment, it is recommended to clarify the disease under the guidance of a doctor.
