If ultrasonography reveals dense or dense echogenicity in the liver, this is a sign of impaired liver function. The most common is after drug-related hepatitis, such as in patients with tuberculosis, where years of oral anti-tuberculosis drugs have a damaging effect on the liver, leading to the deposition of fat in the hepatocyte membrane and the appearance of echogenic densities. In this case, anti-tuberculosis treatment should be accompanied by systematic application of liver-protective drugs and, if necessary, discontinuation of tuberculosis drugs in severe cases. Another condition is chronic viral hepatitis that does not heal for a long time, and repeated attacks can lead to fatty deposits in the hepatocyte membrane, which can affect the metabolism of transaminases and lead to increased transaminases and bilirubin. Ultrasonography may also reveal dense echogenicity, in which case systemic antiviral and symptomatic treatment such as liver protection should be given.
