The Vein of Galen is a major draining vein of the
Brain and is located deep within the center region of the
Brain. This lesion is usually identified on neuroimaging studies
as a large vascular "mass" in the region of the Pineal Gland. "Vein
of Galen Aneurysms" are not true aneurysms but more
accurately described as Galenic Arteriovenous Malformation.
Aneurysms of the Vein of Galen usually produce symptoms at,
or very soon after, birth. This condition is frequently
associated with Hydrocephalus (an accumulation of fluid within
the Ventricles of the Brain where Cerebrospinal Fluid [CSF] is
The affected child will have visible enlargement of the head,
swollen veins on the scalp, seizures, failure to thrive, and congestive
heart failure. Children born with this condition who survive past infancy
often remain developmentally impaired.
Dr. Lazar has reported some of his experience with this difficult problem
in the scientific literature.
