A Successful Treatment of Coexistent Trigeminal Neuralgia and Ipsilateral Superior Cerebellar Artery Aneurysm.J Craniofac Surg. 2015 Jun; 26(4):1270-2.JC
A 71-year-old woman had presented to our clinic with the history of trigeminal neuralgia involving the second and third divisions on the right side. The magnetic resonance tomography angiography examination before operation revealed that the root of the right trigeminal nerve was compressed by the superior cerebellar artery (SCA) artery. During the operation, a fusiform aneurysm was visualized at the distal portion of the SCA. The symptoms of pain disappeared after the surgery of microvascular decompression and the wrapping of the SCA aneurysm. Trigeminal neuralgia coexisting with the aneurysm of the ipsilateral SCA is extremely rare, and it has not been reported before.
