We report a case of infantile hepatic hemangioendothelioma in an eight month-old boy showing,
on the sonogram, a well demarcated hypoechoic mass lesion with internal thin echogenic structures
and central calcifications on the right lobe of the liver. On the periphery of the tumor, both the
enlarged right hepatic vein and the right portal vein were seen in direct communication with the
A subsequent angiographic study confirmed the nature of these vessels and demonstrated the
existence of P-V shunting previously seen by ultrasound. It is the first time that the presence of
P-V shunting was detected by sonography.
In particular, we stress the importance of focussing attention on the relationship between the
tumor and neighbouring vascular structures, since sonography can easily show how it contrasts with
other hepatic tumors in children.
