Benign vascular tumors of the liver in infants: sonographic appearance

Abstract

The distinctive sonographic appearance of benign vascular tumors of the liver (one hemangioendothelioma and two mesenchymal hamartomas) in three infants is presented. Each child had hepatomegaly and congestive heart failure, and all had confirmatory arteriography. The sonographic pattern of a complex mass, dilated proximal aorta, and enlarged nutritive and draining vascular structures should alert the radiologist and clinician to this diagnosis.
