[Congenital vascular malformations in childhood]

The intracranial congenital vascular pathology, arterial, arteriovenous and venous, is reviewed, including the cavernomas as well. It is commented the possible origin, the clinical, histological and neuroradiological alterations as well as the possible treatment, when necessary, of every entity. The contribution of the magnetic resonance (MR), especially the angiographic MR (AMR) has been conclusive to the diagnosis. There have been considered six main groups which include the main entities: 1. Arterial anomalies; 2. Arteriovenous malformations; 3. Malformations of the Galen vein; 4. Venous malformations, and 5. Intracranial cavernomas.
