RT Journal Article SR Electronic T1 Sarcoidosis of the nervous system JF Practical Neurology JO Pract Neurol FD BMJ Publishing Group Ltd SP 234 OP 244 DO 10.1136/jnnp.2007.124263 VO 7 IS 4 A1 F G Joseph A1 N J Scolding YR 2007 UL http://pn.bmj.com/content/7/4/234.abstract AB Although sarcoidosis is rarely confined to the nervous system, any neurological features that do occur frequently happen early in the course of the disease. The most common neurological presentation is with cranial neuropathies, but seizures, chronic meningitis and the effects of mass lesions are also frequent. The diagnostic process should first confirm nervous system involvement and then provide supportive evidence for the underlying disease; in the absence of any positive tissue biopsy, the most useful diagnostic tests are gadolinium enhanced MRI of the brain and CSF analysis, although both are non-specific. The mainstay of treatment is corticosteroids, but these often have to be combined with other immunosuppressants such as methotrexate, hydroxychloroquine or cyclophosphamide. There is increasing evidence that infliximab is a safe treatment with good steroid sparing capacity.
