Cerebrofacial Venous Metameric Syndrome Mimicking Vein of Galen Aneurysmal Malformation

Abstract

Cerebrofacial venous metameric syndrome (CVMS) is a complex low-flow vascular malformation affecting bone and soft tissues including brain, dura mater, and eye. We show images of CVMS in an 18-month-old boy presenting facial venous malformations, developmental venous anomalies, dural sinus malformations, and dilated great cerebral vein, suggesting a vein of Galen aneurysmal malformation. Although Sturge-Weber syndrome is the most known form of CVMS, its presentations are variable and include several venous malformations. Recognizing the various manifestations of CVMS is necessary for adequate screening, treatment, and follow-up.
