title: Perirenal hemangioendothelioma in a newborn: sonograph and MR findings.
abstract: This is a case report of perirenal hemangioendothelioma in a newborn and discussion of lesions in the perirenal space in newborns. The findings in this case, high echogenicity on sonographic images and high signal intensity on T2-weighted spin echo magnetic resonance images, mimic those described for hemangiomas in other locations.
