Infantile hemangioendothelioma of liver

Abstract

Radiologic findings of hemangioendothelioma of the liver were retrospectively analyzed in twelve infants. The radiological examinations included were sonography in 12 patients, computed tomograpy (CT) in six, magnetic resonance (MR) imaging in five, and angiography in two. Four patients were diagnosed pathologically, two by angiography, five by follow-up sonography, and one by clinical presentation with sonography. The common radiologic findings of the hemangioendothelioma were well circumscribed heterogeneous echogenic mass (75%) on sonography, peripheral massive enhancement (67%) on CT, bright high signal intensity on T2-weighted MR image (100%), and homogenous or peripheral enhancement (75%) on Gd-DTPA enhanced T1-weighted MR image. Dilated proximal aorta and enlarged draining hepatic veins on angiography an d other studies were also important findgdings. The follow-up sonography demonstrated the involution of lesions with some calcification in four patients and complete resolution in one. The authors believe that these findings in an under the age of 6 months strongly suggest the diagnosis of hemangioendothelioma of the liver, and follow-up sonography should be done.
