Abstract

Purpose: To assess prospectively how often contacts are found between the trigeminal nerve and arteries or veins in the perimesencephalic cistern via MRI in normal volunteers. Materials and Methods: 48 volunteers without a history of trigeminal neuralgia were examined prospectively (MRI at 1.5T; T2-CISS sequence, coronal orientation, 0.9 mm slice thickness). Two radiologists decided by consensus whether there was a nerve-vessel contact in the perimesencephalic cistern. Results: In 27% of the volunteers, no contact was found between the trigeminal nerve and regional vessels, while in 73%, such a contact was present. In 61% of the cases, the offending vessel was an artery, in 39%, it was a vein. In 2 volunteers, a deformation of the nerve was noted. Conclusion: Contrary to what has been suggested by retrospective studies, the majority of normal volunteers, if studied prospectively, do show a contact between the trigeminal nerve and local vessels. A close proximity between the nerve and regional vessels is thus normal and is not necessarily proof of a pathological nerve-vessel conflict.
