Case report: Primary ependymoma of the trigeminal nerve presenting as trigeminal neuralgia.

BACKGROUND

Ependymomas are usually found in the posterior fossa originating from the fourth ventricle. Primary ependymomas arising from cranial nerves are rare with only a handful of reported cases. Trigeminal neuralgia (TN) is rarely due to space occupying lesions.

CASE DESCRIPTION: A 20-year-old female presented with TN with a rare presentation of a pure extra-axial ependymoma involving the right trigeminal nerve in the cerebellopontine angle.

CONCLUSION

It is essential to explore the possibility of a mass arising from the trigeminal nerve when investigating the cause of TN.
