Peripapillary choroidal neovascularization (PPCNV), a rare presentation of optic nerve sheath meningioma (ONSM), is associated with various ocular pathologies. Herein, we report a case with characteristics of age-related macular degeneration, PPCNV, optic disc edema, and a retinal–choroidal venous collateral. In addition to the recognition of an orbital base ONSM, magnetic resonance imaging revealed a distended perioptic subarachnoid space with the accumulation of cerebrospinal fluid anterior to the tumor. On the basis of these clinical findings, we postulated the pathogenesis of PPCNV-associated ONSMs.
