title: Optic neuropathy and cerebral sarcoidosis.
abstract: An intracranial mass lesion is a rare, but reported presenting sign in sarcoidosis. A 39-year-old woman presented with a frontal lobe lesion (pathologically a noncaseating granuloma) associated with chronic progressive visual loss and optic atrophy on the right side. High-resolution axial and coronal computerized tomography revealed a parachiasmal density compatible with the clinical course. Clinical suspicion of granulomatous processes and appropriate workup in all cases of optic neuropathy may allow for early medical therapy in such cases.
