Pedunculopontine nucleus deep brain stimulation in a patient with primary progressive freezing gait disorder.

abstract：:Background: Trigeminal neuralgia (TN) is mostly caused by vascular compression of the nerve's root entry zone due to an ectatic artery. Rarer causes include compression from tumors, vascular malformations or multiple sclerosis plaques. Developmental venous anomalies (DVAs) are benign, aberrantly appearing venous struc...
