1Department of Neurosurgery, Aga Khan University Hospital, Karachi, Pakistan.
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.
