BACKGROUNDVein of Galen aneurysmal malformations (VGAMs) are rare congenital intracranial vascular lesions that represent 30% of all pediatric vascular anomalies. These lesions are associated with severe manifestations, including congestive heart failure, hydrocephalus, and spontaneous hemorrhage. The mainstay of management is medical stabilization followed by endovascular embolization of the lesion. Although VGAM was first reported in 1937, there are few published cases demonstrating spontaneous regression of the lesion.OBSERVATIONSThe authors report the case of a 31-month-old female who presented with an incidentally found VGAM. After initial evaluation, including magnetic resonance imaging and angiography, the patient was lost to follow-up. Upon her return to the clinic at age 12 years, the previously identified VGAM was absent, indicative of involution of the lesion. The patient remained asymptomatic and met appropriate developmental milestones during this interval.LESSONSThis report adds a rare case of the spontaneous resolution of VGAM to the literature. This case may suggest the presence of VGAMs that are asymptomatic, undetected, and regress within the pediatric population. Future studies may benefit from identifying imaging and angiographic findings predictive of spontaneous regression. There may be a role for conservative management in particular cases of asymptomatic and medically stable children with VGAMs.

Spontaneous regression and complete disappearance of the vein of Galen aneurysmal malformation

Abstract: Different conditions including hemodynamic alteration, compression of adjacent hematoma, and narrowing of related vascular structures have been described to cause thrombosis of VoGAM. The relevant literature to address possible mechanism is reviewed.
