Neurosarcoidosis is a rare complication of sarcoidosis and typically presents as acute cranial neuropathies. Neurosarcoidosis can rarely cause an inflammatory optic neuropathy, resembles an optic neuritis and even more rarely can cause an optic perineuritis. Although concomitant optic neuritis and optic perineuritis have been reported in other inflammatory conditions, such as myelin oligodendrocyte antibody-associated disease, spatially-distinct optic neuritis, and optic perineuritis has not been previously described in neurosarcoidosis. Here, we present a case of spatially-distinct concomitant optic neuritis and optic perineuritis from neurosarcoidosis in a 51-year-old man initially suspected to harbor metastatic disease based on imaging findings.
