What causes Wallenberg syndrome?

The most common cause of Wallenberg syndrome is stroke in the vertebral or posterior inferior cerebellar arteries of the brain stem (brain stem stroke).[1][2] However, several other disorders or conditions have also been reported as being associated with Wallenberg syndrome, including mechanical trauma to the vertebral artery in the neck, vertebral arteritis (inflammation of the walls of the arteries), metastatic cancer, hematoma, aneurysm of the vertebral artery, herpetic brainstem encephalitis, head injury, arteriovenous malformations (AVMs), multiple sclerosis, varicella infection and brainstem tuberculoma (a rare form of tuberculosis).[2][3][4][5][6]
