Volumetric Measurement of the Pontomesencephalic Cistern in Patients with Trigeminal Neuralgia and Healthy Controls

Abstract

High-resolution magnetic resonance imaging scans are able to demonstrate significant volumetric differences of the pontomesencephalic cistern in patients with unilateral TN. A smaller cistern may be correlated with the occurrence of a neurovascular compression, and these findings support the neurovascular compression theory in idiopathic TN.
