Objective: To differentiate diffuse liver cancer from portal cirrhosis by using ultrasonography. Methods: We analyzed the sonographic images of 15 patients with diffuse liver cancer and 30 patients with portal cirrhosis. Results: The patients with diffuse liver cancer showed enlarged liver and obvious echo of nodules. The rate of portal embolism and swelling of lymph nodes a- round the porta hepatis was high. The patients with portal cirrhosis showed diminished liver and the obvi- ous echo of fiber proliferation. The rates of spleen enlargement and ascites as well as gallbladder edema were high. Conclusions: To identify sonographic characteristics inside and outside of the liver. It is helpful in diffe- rentiating diffuse liver cancer from portal cirrhosis. The sonographic characteristics inside the liver in- clude surface and size, node echo, echo of fibrous tissue hyperplasia. They are difficult to identify when diffuse liver cancer merges with considerable cirrho- sis. The acoustic image characteristics of the two di- seases overlap. Hence attention should be paid to the size of the liver, proliferation of cells of diffuse liver carcinoma. In sonographic characteristics outside the liver, embolism of the portal vein and swelling of lymph nodes in the porta hepatis are particularly use- ful to identify diffuse liver cancer or diffuse liver cancer combined with liver cirrhosis in particular.
