Rare Galen Vein Aneurysm in a 40-Year-Old Woman: In-Depth Analysis of an Exceptional Case

Vein of Galen aneurysm is a rare vascular condition commonly diagnosed in children. This type of aneurysm arises from the persistence of the embryonic median prosencephalic vein, precursor to the Galen vein. This paper highlights the rarity of this phenomenon in a 40-year-old woman. The aim of this study is to demonstrate that conservative treatment of this malformation can be a valid option in oligosymptomatic cases without signs of hydrocephalus. While the literature emphasizes interventional procedures as the primary choice, especially arterial embolization, this case underscores the relevance of conservative treatment, particularly in neurologically stable patients.
