Key take away

The use of magnetic resonance neurography is suitable for diagnosing and managing trigeminal neuralgia. Both microvascular compression and the conditions of peripheral branches of the trigeminal nerve should be emphasized during the diagnosis of trigeminal neuralgia.

Background

A study aimed to find the effectiveness of magnetic resonance (MR) neurography to diagnose and manage trigeminal neuralgia.

Method

Overall, fifty-five patients clinically diagnosed with trigeminal neuralgia were imaged with 3.0-T MR imaging. The thorough course of the trigeminal nerve was revealed via the images. The clinical outcomes included mean duration of symptoms (41.99 months) and visual analog scale (VAS) pain score (5.98).

In this cohort study, the final diagnoses were inflammation (21), microvascular compression (19), microvascular compression with inflammation (5), normal (5), injury to peripheral nerve (2), multiple sclerosis (2), and tumor (1).

Result

MR neurography had a considerable impact on diagnosis and treatment in 56.4% of patients with trigeminal neuralgia. Thirty-three patients underwent intervention for pain. MR neurography had a significant effect on 54.5% of the patients.

MR neurography results were considerably linked with intervention with an outstanding response in 19 patients (57.6%) and moderate in 14 patients (42.4%). Many patients (75.8%) witnessed pain relief following the surgery or interventional practice.

Conclusion

MR neurography had a positive effect on diagnosis and clinical management of trigeminal neuralgia with a moderate-to-excellent association with intervention response.
