Hypoechoic right lobe of the liver is not necessarily liver cancer, benign liver diseases can also show this sign, and CT, MRI and other tests are needed to confirm the diagnosis of liver cancer. Hypoechoic right lobe of the liver is an imaging description of liver ultrasound, and normal liver tissues appear as uniform echoes in ultrasound examination. Hypoechoic right lobe of the liver suggests that there may be a mass in the right lobe of the liver that is less dense than the surrounding normal tissue. This sign is usually seen in benign lesions such as hepatic cysts and hepatic hemangiomas, and also in some cases of hepatocellular carcinoma. Therefore, one should not diagnose liver cancer only based on right lobe hypoechoic echo, but also need to undergo CT, MRI, hepatic arteriography and other imaging tests, as well as tumor markers such as alpha-fetoprotein, CA199, etc., to be diagnosed by a professional doctor.
