Background:
Ectopic orbital meningiomas (OM) are a rare subset of OMs which are neither attached to the optic nerve sheath nor to the surrounding bone.
Case Description:
We report the case of a 65-year-old female who presented with a 1 year history of proptosis followed by visual loss and restricted right eye movements since 3 months. Radiology of the orbits was suggestive of intraorbital, intraconal, and heterogeneous contrast enhancing right eye lesion which was completely excised through supraorbital orbitotomy approach. Intraoperatively, the right optic nerve, though compressed, and displaced inferiorly, was free from the lesion. The final histopathological diagnosis was "Meningioma WHO Grade I." At 3 months follow-up, patient's vision in the right eye improved from perception of light positive to 6/12 and there was no evidence of recurrence.
Conclusion:
Rarity of ectopic OM, total surgical excision with an excellent postoperative visual outcome prompted us to report this case.
