What is the most common cause of increased hepatic echogenicity?
Increased hepatic echogenicity is detected when the liver is considerably more echogenic than the kidney. The most common cause is hepatic steatosis. Other sonographic features of hepatic steatosis include finer and more compact echotexture and decreased transmission of sound waves such that the deeper aspect of the liver is difficult to visualize, as are the adjacent diaphragm and intrahepatic vessels. There are numerous causes of hepatic steatosis, including obesity, alcohol abuse, diabetes mellitus, corticosteroid use, malnutrition, and chemotherapy.
