Abstract. Purpose:To report a case of hypertrophic pachymeningitis with bilateral optic neuropathy as the initial manifestation. Case:A 65-year-old female presented with impaired visual acuity and field defect since 3 weeks before. Findings:Corrected visual acuity was 0.2 right and hand motion left. Gadolinium-enhanced MRI showed thickening of dura mater in the frontal lobe and intense signal around the optic tract. Biopsy of the dura led to the diagnosis of hypertrophic pachymeningitis. Pulsed corticosteroid therapy with tapering prednisolone was followed by decreased thickness of dura mater, improved visual acuity to 1.0 in either eye, and normalization of visual field. Conclusion:This case illustrates that hypertrophic pachymeningitis may show symptoms simulating retrobulbar neuritis. Enhanced MRI may be useful in the diagnosis.
