RESUMO
At de National Institute of Pediatrics in Mexico City, the ultrasonographic findings of hepatoblastomas were analyzed in order to establish the echographic pattern of this malignant liver tumor. The ultrasonic images of patient's livers dating back six years were retrospectively reviewed. The hyperrecognisance of the hepatoblastoma as a solid, poorly limited mass, with or without the presence of calcifications, with the displacement of the portal vein and frequently found in the right lobe, were considered as the most relevant echographic characteristics of the hepatoblastoma. The echographic characteristics found of the hepatoblastoma can aid in the sonographic diagnosis of the disease. The leukemic liver infiltrations, the primary liver lymphoma and the metastasis, due to their hyperrecognisance, can be confused with the diagnosis of hepatoblastoma.
