title: Case series: non vascular considerations in trigeminal neuralgia.
abstract: An abnormal vascular course of the superior cerebellar artery is often cited as the cause for trigeminal neuralgia. However, among patients with TN-like symptoms, 6% to 16% are variously reported to have intracranial tumours. Aneurysms, tumours, or other lesions may impinge or irritate the trigeminal nerve along its course. Uncommonly, an area of demyelination from multiple sclerosis may be the precipitant. We would like to present a series of unusual lesions, all of which initially presented with neuralgic-like symptoms and were refractory to treatment. Collated case series with photographs and imaging are reviewed in this paper. Discussion of case presentation and management are done for evaluation. A wide range of other compressive lesions can cause trigeminal neuralgia. This paper illustrates the clinical presentation of atypical trigeminal neuralgia and emphasises the value of diagnostic imaging in trigeminal neuralgia patient. Suggested algorithm for management of trigeminal neuralgia.
