Trigeminal Neuralgia Caused by Nerve Compression by Dilated Superior Cerebellar Artery Associated with Cerebellar Arteriovenous Malformation: Case Report
نویسندگان
چکیده
Intracranial arteriovenous malformation (AVM) is a rare cause of trigeminal neuralgia (TGN). In this presented case, successful resolution of AVM-related TGN following embolization and gamma knife stereotactic radiosurgery (GKRS) was obtained. A patient suffered from TGN on the left side, which was thought to be caused by root entry zone compression by dilated superior cerebellar artery (SCA) associated with cerebellar AVM. The cerebellar vermis AVM was embolized in endovascular surgery. The AVM was reduced in size and TGN was partially relieved. The patient subsequently underwent GKRS for the residual nidus. TGN was completely resolved within one year and a half. GKRS following embolization of the nidus improved the flow-related dilation of the SCA and completely relieved TGN.

Secondary Trigeminal Neuralgia Caused by a Tentorial Dural Arteriovenous Fistula: A Case Report and Literature Review
Trigeminal neuralgia caused by a tentorial dural arteriovenous fistula has rarely been reported. The mechanism underlying the development of trigeminal neuralgia has been reported to be the compression of the root entry zone by the arterialized draining vein. However, the cases showing refractory or recurrent neuralgia could imply the presence of another underlying mechanism. We herein describe...
متن کاملIntrinsic arteriovenous malformation embedded in the trigeminal nerve of a patient with trigeminal neuralgia.
A 66-year-old man presented with typical right trigeminal neuralgia. Neuroimaging showed a small arteriovenous malformation (AVM) in the right cerebellopontine angle. Suboccipital craniotomy verified that the AVM was almost completely embedded in the root entry zone of the trigeminal nerve and the nerve axis was tilted infero-posteriorly. The patient obtained complete pain relief without sequel...

Few cases of trigeminal neuralgia (TGN) induced by brain arteriovenous malformations (bAVMs) have previously been reported. The present case report described one case of TGN caused by bAVMs in a 32-year-old male patient who suffered from recurrent pain in his right cheek for a period of two years, for whom the seizure frequency and duration of pain increased for 6 months. Magnetic resonance ima...
متن کاملTrigeminal Neuralgia Due to Red Vein Draining a Supratentorial Arteriovenous Malformation: Case Report
Trigeminal neuralgia (TGN) is rarely caused by arteriovenous malformation (AVM). The AVMs causing TGN are reported mostly in the ipsilateral posterior fossa. The culprit vessels are dilated feeding artery or nidus itself. We present a rare case of TGN caused by dilated draining veins from a supratentorial AVM. The patient suffered from TGN with an incidentally found large AVM, which had been le...

One of the mechanisms suggested for the etiology of trigeminal neuralgia is compression and’ distortion of the nerve in the pontine zone by the superior and anterior inferior cerebellar arteries or their branches. Conflicting reports have been presented by various workers on this issue. The present study was conducted on cadaveric specimens. The superior cerebellar artery was found to be in con...
