Arteriovenous malformation — is a congenital vessel abnormality that is characterized by pathologic arterial and venous plexuses formation within the brain without capillary web between them. These malformations can have no clinical presentation or can reveal themselves as intracranial haemotomas against the background of subarachnoid and/or intraventricular hemorrhage.
