10 Causes of Trigeminal Neuralgia
Cause #4: Arteriovenous Malformation
Arteriovenous malformation refers to a network or connection of abnormal arteries and veins that bypasses the capillary system. While many are asymptomatic, they can also cause serious issues such as bleeding and intense pain. Most arteriovenous malformations are congenital.
The signs and symptoms for an arteriovenous malformation depend on the location of the malformation. Most are discovered as part of an incidental finding. Those in the brain can result in neurological deficit, epilepsy or pain. If one happens to compress the trigeminal nerve, it can also cause trigeminal neuralgia.
