title: Trigeminal Neuralgia Completely Relieved After Stent-Assisted Coiling of a Superior Cerebellar Artery Aneurysm.
abstract: BACKGROUND
  Although secondary trigeminal neuralgia is usually due to tumors or multiple sclerosis, other major neurologic diseases, such as aneurysms, should be taken into account when the history or the symptoms suggest a secondary origin.
  
  
  METHODS
  A 67-year-old lady presented with a 6-month history of trigeminal neuralgia involving exclusively the right ophthalmic division. A dedicated 3-dimensional-magnetic resonance imaging-magnetic resonance angiography study documented rare contact with a wide-necked aneurysm of the superior cerebellar artery, which distorted the trigeminal root. The patient underwent an endovascular treatment by stent-assisted coiling with the complete disappearance of neuralgic pain attacks within 24 hours.
  
  
  CONCLUSIONS
  The complete relief from the neuralgic paroxysms immediately after endovascular stent-assisted occlusion of a superior cerebellar artery aneurysm demonstrates the crucial role of a pulsating stimulus on the demyelinated nerve fibers in evoking the ectopically generated discharges.
