A 55yr old female presented with left eye proptosis which was painless, gradual, progressive and not associated with double vision or any history of trauma. No history of thyroid disease. BCVA in right eye 20/20, left eye 20/80. Hertel’s exophthalmometry readings were right eye 12mm, left eye 20mm.Left eye showed normal optic disc with 0.4 cup disc ratio with mild elevation nasal and superior to disc and retinal folds temporal to disc(Paton’s lines).LE SD optical coherence tomography demonstrates a reduction of the peripapillary Retinal Nerve Fibre Layer and ganglion cell layer, as well as paton's lines temporal to the disc, elevation nasal and superior to the disc. MRI showing well defined spindle shaped lesion measuring 2.3 x 1.3 cm in intraconal compartment of left orbit arising from optic nerve sheath hypo intense on T1W and hyper intense on T2W suggestive of optic nerve sheath meningioma.
