Cerebral Arteriovenous Malformation

A cerebral arteriovenous malformation is a condition whereby there is an abnormal connection between the arteries and veins in the brain. While their cause is unknown, cerebral arteriovenous malformations are rare and usually form during pregnancy or immediately after birth.

Symptoms of Cerebral Arteriovenous Malformations

The first symptom in about 50% of the people who are diagnosed with cerebral arteriovenous malformations is a stroke caused by bleeding in the brain.

Cerebral arteriovenous malformations can happen anywhere in the body but are most commonly found in the brain or spinal cord. Most people diagnosed with brain or spinal cerebral arteriovenous malformations have few major symptoms, if any.

Symptoms of a cerebral arteriovenous malformation that is bleeding:

  • Confusion
  • Ear noise/buzzing (also called pulsatile tinnitus)
  • Headache in one or more parts of the head that may seem like a migraine
  • Problems walking
  • Seizures

Symptoms of a cerebral arteriovenous malformation that is putting pressure on one area of the brain:

  • Dizziness
  • Muscle weakness in an area of the body or face
  • Numbness in an area of the body
  • Vision problems
