An aneurysm of the vein of Galen is a rare midline arteriovenous malformation. The clinical signs and the prognosis strictly depend on age of presentation and on the amount of blood shunted into the malformation. In the newborn, cardiac failure is the most common presenting sign. ⋯ Computed tomography also added useful information on associated hydrocephalus and ischemic brain damage. The dilated vein of Galen, straight sinus and torcular were clearly seen. Abnormal arterial vessels feeding the malformation were also recognized.
