[Echography and computed x-ray tomography in the diagnosis and surveillance of hepatoblastoma. Apropos of 5 cases].

Ultrasound imaging and CT scans were performed in a homogeneous group of five patients with hepatoblastoma. Effectiveness in determining characteristics of the tumor mass and its location and possible vascular extension were compared for the two exploratory methods. Findings suggest that these two examinations are useful and complementary for the diagnosis and follow up of hepatoblastoma.
