CT shows that the left lobe of the liver is enlarged, the right lobe is small, and the edge of the liver is wavy, which is a typical manifestation of cirrhosis, and it is closely related to the repeated injury and regeneration of liver tissue. Clinically, after hepatitis and long-term liver injury, there will be regeneration of hepatocytes and formation of pseudo lobe, and repeated injury and regeneration process will lead to the formation of cirrhosis. CT examination reveals a disproportion between the left and right lobes of the liver, with the left lobe of the liver enlarging and the right lobe of the liver decreasing in size, and the edges of the liver are not smooth, showing wave-like changes. After the discovery of cirrhosis, we should pay attention to monitoring the changes of liver function and liver tissue changes, and once an abnormal mass is found in the liver, we need to consult a doctor in time to investigate the possibility of liver cancer, and carry out standardized treatment under the guidance of the clinician, so as to avoid the delay of the condition.
