Treatment of central nervous system sarcoidosis with radiotherapy.

This report documents the twelve-year follow-up of a patient with neurosarcoidosis with multiple progressive central nervous system manifestations. Increased somnolence and seizure activity were associated with proliferation of nodular enhancing brain lesions, as seen on serial computed tomographic (CT) scans. Initially he responded to corticosteroid treatment, but gradually this response became unsatisfactory. After whole-brain irradiation with a total dose of 3,000 rads, his clinical symptoms improved with disappearance of the enhancing brain lesions seen on CT scan.
