Objective: To investigate the CT features and differential diagnosis of hepatoblastoma in children. Methods: CT features of 18 cases of hepatoblastoma in children confirmed by clinical and pathology were retrospectively analyzed. The clinical and pathological findings were analyzed. Results: The tumor located in the right lobe of the liver in 13 cases, 3 cases of left lobe of liver, diffuse in 2 cases, including tumor growth to the liver margin in 4 cases; round and oval large tumor in 13 cases, lobular fusion nodules in 4 cases, 1 There were multiple scattered nodules in the cases; 12 cases were marginalized and 6 were marginalized; 15 cases had intratumoral calcification, 5 cases had intratumoral hemorrhage, and 3 cases had intratumoral calcification with hemorrhage.
