Optic nerve sarcoidosis: MR findings.

Abstract

Neurologic involvement has been described in 5% of patients with sarcoidosis; however, direct granulomatous involvement limited to the optic nerve but not involving the chiasm is rare. We describe two patients with biopsy-proven sarcoidosis; the fat-suppressed gadolinium-enhanced MR findings showed sarcoid involvement limited to the optic nerves.
