Sarcoidosis is an idiopathic multisystem granulomatous disorder. Neurologic manifestations in sarcoidosis are varied and making a diagnosis of neurosarcoidosis can be difficult as it mimics various other neurologic diseases. ⋯ Definitive diagnosis requires neurologic tissue evidence of noncaseating granuloma, but in practice probable diagnosis is often made through nonneurologic biopsy and a characteristic syndrome and imaging. Treatment remains empiric, but new advances in immunologic therapy hold promise for effective and less-toxic regimens.
