Fifty consecutive patients with neurosarcoidosis were evaluated retrospectively. Sarcoidosis presented first with neurologic signs in 24 patients (48%), but systemic symptoms developed later in all but five. Main neurologic involvements were central nervous system lesions in 33 patients (66%), cranial nerve paresis in 12 (24%), and peripheral nerve lesions in five patients (10%). Seventeen patients (34%) had more than one type of neurologic involvement. Routine cerebrospinal fluid (CSF) parameters showed unspecific abnormalities in 35 patients (70%). CSF angiotensin converting enzyme was elevated in 18 of 31 patients (58%). Brain computerized tomography was abnormal in 13 of 32 patients (41%). Visual and brainstem evoked potentials were abnormal in ten (43%) and eight (35%) of 23 patients, respectively, suggesting subclinical lesions in 13 patients. Neurologic signs improved in 24 patients (48%), were stable in 11 (22%), and progressed in 15 patients (30%). Six patients died. Cranial nerve lesions improved most often. Course of neurologic involvements was similar in acute or subacute and chronic sarcoidosis. The effect of steroid treatment was inconsistent.
