Abstract
Vein of Galen malformations (VGAMs) are rare and complex congenital brain vascular anomalies that pose significant diagnostic and treatment challenges. The natural history of this type of vascular anomaly is very poor, with many patients succumbing to complications such as congestive heart failure, hydrocephalus, and brain parenchymal injury. Although the clinical course of most VGAMs was considered unfortunate, with meticulous imaging, a group of lesions with a more placid presentation and course can be identified.
We present a case of spontaneous thrombosis of VGAM where no embolization or surgical repair was attempted, with excellent clinical outcomes.
This case also highlights the possibility of spontaneous thrombosis in VGAM, even in the absence of clinical symptoms, and emphasizes the importance of a regular imaging follow-up in patients with known vascular malformations.
