Painful tic convulsif caused by a contralateral vertebral artery.
The case of trigeminal neuralgia and ipsilateral hemifacial spasm--painful tic convulsif--is presented. Microsurgical exploration revealed compression of the fifth and seventh cranial nerves by a tortuous contralateral vertebral artery. Neurovascular decompression of the roots entry/exit zone completely relieved preoperative facial pain and spasm.
