Arteriovenous Malformation Presenting as Trigeminal Neuralgia

Posterior fossa arteriovenous malformations

“…The association of trigeminal neuralgia and AVM's has been reported previously. 7,14,25,26 Five patients presented with difficulties unrelated to hemorrhage 61 with ruptured aneurysm 9 with unruptured aneurysm 3 headache 3 focal neurological deficit 2 hemorrhage. During an investigation for headaches, three patients were found to have intact AVM's.…”

Trigeminal Neuralgia in a Patient with a Dural Arteriovenous Fistula in Meckel's Cave: Case Report

“…Other arteries, such as the anteroinferior cerebellar artery (10%), posteroinferior cerebellar artery (1%), vertebral artery (2%), basilar artery (1%), and primitive trigeminal artery or its variants, have also been implicated (5,27). Tumors (38,42), aneurysms (9,24,26), vascular malformations (1,21,25,26,38,42), or vertebrobasilar artery ectasia (23) is observed in only a minority of cases.…”

Neurovascular relationships in the posterior cranial fossa, with special reference to trigeminal neuralgia. 2. Neurovascular compression of the trigeminal nerve in cadaveric controls and patients with trigeminal neuralgia: Quantification and influence of method

“…The condition is usually unilateral and must be differentiated from other forms of facial pain (Penman, 1968;Illingworth, 1986;Rasmussen, 1990aRasmussen, , 1990bRasmussen, 1991aRasmussen, , 1991b. A small percentage of cases have been secondary to compressive lesions lying in the cerebellopontine angle and some are related to multiple sclerosis (Johnson and Salmon, 1968;Wegrzyn, 1983;Kapila et al, 1984;Sugita et al, 1986;McCormick et al, 1988;Hakusui et al, 1991). Others have an apparent oral cause (Ratner et al, 1979;Nordh and Nordh, 1982;Zurak, 1990).…”
