This study demonstrates vascular compression characteristics in trigeminal neuralgia patients, suggesting implications for MRI diagnostics.

Compression by the superior cerebellar artery was detected in 69 cases, revealing important localization patterns.
On the side with trigeminal neuralgia, vessels were found only 1.56 mm away from the brainstem on average, indicating proximity issues.
MRI-based measurements revealed that compression points were often less than half the width of the trigeminal root.
Unilateral vascular compression was documented in all TN cases, calling attention to the need for careful preoperative evaluations.

Grigoryan et al. (2025) studied this question.
