Sarcoidosis of the eye, orbit, and central nervous system - Role of MR imaging

Sarcoidosis, a systemic disease of unknown cause, frequently involves the e ye, orbit, and central nervous system. The MR imaging findings of orbital a nd optic pathway sarcoidosis may closely resemble several other orbital and intracranial diseases. This article reviews MR imaging findings of sarcoid osis when it involves the eye, orbit, and visual pathways. Careful review o f MR findings and other neuroimaging findings and clinical characteristics will reduce the incidence of mistaking optic nerve and chiasmal sarcoidosis for meningioma or glioma.
