Dense diffuse punctate enhancement of intrahepatic echoes is an ultrasound term. Dense diffuse punctate enhancement of intrahepatic echoes may be associated with acute viral hepatitis, diffuse fatty liver, cirrhosis, and so on. 1. Acute viral hepatitis: Viral hepatitis is an infectious disease caused by different types of hepatitis viruses, with degeneration and necrosis of hepatocytes as the main lesions. Its ultrasonography shows that the liver is enlarged to different degrees, and the angle of the liver margin is blunted. The hepatic parenchyma is uniformly echogenic, with dense fine dot-like echoes. The walls of the hepatic portal vein and bile ducts are enhanced. 2. Diffuse fatty liver: mainly due to the disorder of normal lipid metabolism pathway, excessive accumulation of neutral fat and lipid deposits in hepatocytes, which is more than the physiological content of reversible changes. Ultrasonography shows that the liver size is normal, or mildly to moderately enlarged, the left and right lobes of the liver show diffuse and dense distribution of tiny dot-like echoes, the distribution of intrahepatic echoes is not uniform, and the transmittance of the whole liver area is reduced. 3. Cirrhosis: it is a common chronic progressive liver disease, with diffuse liver damage formed by long-term or repeated effects of one or more causes. Ultrasonography shows that the hepatic parenchyma is diffusely elevated, with dense, denser dots of different sizes, and coarse granular and irregular hyperechoic streaks of corn grain size can be scattered in the liver, with poor translucency. Intrahepatic echogenicity in the form of dense diffuse enhancement of dots can not accurately determine the disease, but also need to be combined with the characteristics of the history, other test results to make an accurate judgment, it is recommended to clarify the disease under the guidance of a doctor.
