Sarcoidosis is a multisystem granulomatous disease of unknown etiology. Neurologic manifestations may occur in 10% of patients with sarcoidosis, either in addition to systemic sarcoidosis or as an isolated presentation, and may be the first clinical manifestation of sarcoidosis. Over 50% of patients with neurosarcoidosis have cranial neuropathy at initial presentation. Optic and facial nerves are most commonly involved.
