“…MRI makes it possible to better specify the anatomical relationships of the malformation, particularly with deep brain structures. In aneurysmal dilatation, arteries and veins are empty of signal on T1 and T2 sequences [3,15]. For our 3 observations, the diagnosis was made by brain CT scan.…”

“…Clinical manifestations depend on the age of discovery and the diagnosis is usually made antenatally on obstetric ultrasound, or in the neonatal period in a congestive heart failure picture, or postnatally. The clinical presentation in adults is exceptional [3]. The prognosis is often poor, with 50% post-natal mortality and a high risk of neurological sequelae [4,5].…”

Background Aneurysm of vein of Galen is a rare congenital arteriovenous malformation. Clinical manifestations depend on the age of discovery. Endovascular embolization is currently the treatment of choice. This technique is not always available in developing countries. We report 3 cases treated symptomatically by endoscopic third ventriculostomy and ventriculoperitoneal shunt. Cases presentation Three patients, 7 months, 15 years, and 26 years old, received in a table of acute intracranial hypertension, associated for the first one with convulsions and for the second one with moderate heart failure. Bain CT scan revealed triventricular hydrocephalus secondary to sacciform dilatation of the Galen’s vein in all three patients, requiring symptomatic treatment by endoscopic third ventriculostomy for the first patient and ventriculoperitoneal shunt for the other two in the absence of an adequate clinical platform for endovascular embolization. The evolution was favorable at 1 year’s follow-up. Conclusion Galen’s vein aneurysm is a rare vascular malformation. It mainly affects newborns and small children but can be discovered in adulthood. Endovascular embolization is its treatment of choice. This technique is not always available in some countries, which makes it necessary to resort to symptomatic treatment by ventricular shunt.
