Is prenatal volumetric evaluation of aneurysm of the vein of Galen important in the prediction of adverse fetal outcome?

Abstract

Aneurysm of the vein of Galen is a rare congenital vascular malformation of the central nervous system. There are controversies in the literature regarding the possible prognostic value of aneurysmal volume estimation with 3-dimensional US for the prediction of fetal outcome. In this report, we present a case of prenatally diagnosed large aneurysm of the vein of Galen complicated by heart failure in a fetus. The volume of the malformation was calculated as 17.8 cm(3) and the fetal outcome was poor.
