Emerging new markers of toxic epidermal necrolysis.

Fetal magnetic resonance imaging (MRI) serves a dual role in the prenatal diagnostic work up of a vein of Galen aneurysmal malformation (VGAM). First, it may confirm the prenatal ultrasound findings and secondly it may identify prognostically important secondary complications of the VGAM. Progressive heart failure with development of fetal hydrops and hemispheric white matter injuries are associated with a poor outcome in children with a VGAM. We present the prenatal findings using both ultrasound and MRI of a fetus with VGAM including bilateral injury of the cerebral hemispheres, severe dilatation of the jugular veins, cardiomegaly, and hydrops fetalis. The neonate died within 30 minutes after delivery. Moreover, fetal MRI revealed complete placenta praevia, uterine fibroids, and wrapping of the umbilical cord around the fetal neck. This additional information is unrelated to the fetal pathology, but could have been of importance to plan the delivery.
