- Arteriovenous malformation (AVM) is a congenital defect of the circulatory system, comprised of a nest of blood vessels.
- AVM is typically detected incidentally during CT or MRI studies.
- Symptoms vary depending on the location of the AVM and the amount of hemorrhage, but can be as general as a seizure or headache.
- The following clinical symptoms commonly occur with AVM bleeds:
- Ataxia - Paresthesia/dysesthia
- Aphasia - Memory deficits
- Confusion - Hallucinations
- Apraxia - Papilladema
- If asymptomatic by the late 40's of life, usually remain stable and asymptomatic.
