Atypical Optic Nerve Sheath Meningioma With Postbiopsy Ophthalmic Artery Occlusion

The authors present the case of a 44-year-old female with progressive optic neuropathy secondary to an atypical posterior intraconal tumor who underwent incisional biopsy complicated by severe postoperative vision loss secondary to ophthalmic artery occlusion. Histology showed a fibroblastic meningioma WHO grade 1. Here, the authors discuss the clinical and radiologic findings, in particular, the exophytic "globular" configuration of the tumor, and perform a review of the literature.
