Aneurysmal malformation of the Galen vein is an uncommon abnormality, comprising less than 1% of all congenital cerebral vascular malformations. However, it accounts for approximately 30% of such malformations in the pediatric population. This condition represents a cerebral arteriovenous malformation that develops prenatally, initiating prior to ten weeks of gestation. It arises from the formation of arteriovenous fistulas connecting the choroidal circulation and the median prosencephalic vein, an embryonic precursor of the Galen vein, which subsequently undergoes dilation. Here, we present an exceptional case of this malformation that was incidentally detected during a Brain CT scan.
