Radiosurgery to the right fifth cranial nerve was performed with the Gamma Knife on a 39-year-old patient who presented with classic symptoms of trigeminal neuralgia (TN), but was found on imaging studies to harbour a small intrinsic vascular malformation within the nerve. Based onsize and drainage, the arteriovenous malformation (AVM) was Spetzler-Martin Grade III and noprevious history of bleeding was reported. The patient had failed atrial of carbamazepine, and no surgical procedures had been performed.A decrease in symptoms was reported by the 6-month follow-up. A review of the literature on microAVM-induced TN is provided as well as a discussion of management.
