title: Embolization of a tentorial dural arterio-venous fistula presenting as atypical trigeminal neuralgia.
abstract: A patient with a tentorial dural AV fistula causing atypical trigeminal neuralgia (TN) successfully treated by embolization is reported. The patient developed persisting throbbing facial pain in the distribution of the second and third division of the right trigeminal nerve (V2, V3) after a history of typical neuralgia for one year, preceded by a two month spell of TN 6 years previously and accompanied by right-sided pulsatile tinnitus for 10 years. The patient's mother, brother and sister were also said to be affected by typical trigeminal neuralgia. A right-sided dilated vein of Rosenthal due to a dural AV fistula fed by branches of the meningeal, occipital and meningo-hypophyseal trunk of the internal carotid artery was thought to cause trigeminal nerve compression. Complete resolution of symptoms after partial intra-arterial embolization of the main feeding arteries with N-butyroacrylate is described.
