Solitary Intracranial Extra-osseous Plasmacytoma Presenting with Ophthalmic Signs

Abstract

Solitary plasmacytomas rarely develop in the skull, meninges, or brain. Ophthalmic signs as the initial manifestations of solitary intracranial plasmacytoma have rarely been described. We report the neuro-ophthalmologic, imaging, and pathologic findings for two patients. One patient presented with optic neuropathy, the second with bilateral sixth nerve palsies. Plasmacytoma is a treatable intracranial tumor that should be considered in the differential diagnosis of patients who present with optic neuropathy or sixth nerve palsy.
