Cerebral Arteriovenous Malformation

A cerebral arteriovenous malformation is an abnormality in which a group of blood vessels in the brain connect abnormally, so that arteries communicate directly with veins without the network of small vessels that normally joins them.

How it shows up: in many cases it causes no symptoms and is discovered incidentally; in others it can cause headaches, seizures, or neurological symptoms.

Why evaluation matters: because it is an abnormal vascular connection, careful study allows each particular situation to be understood.

Which specialist treats it? it falls to the neurosurgeon and the neurologist, with the participation of the pediatrician when it is identified in childhood. If you have been told about a finding of this kind or you have persistent neurological symptoms, the advisable course is to have it evaluated by a specialized professional.
