A case of rheumatoid nodule formation within the central nervous system and review of the literature.
We describe nodule formation within the central nervous system (CNS) in a patient with seropositive rheumatoid arthritis (RA). Review of 13 previous reports of CNS rheumatoid nodule formation suggests that the clinical course is usually one of longstanding seropositive disease. Correlation of neurologic signs and symptoms with anatomic lesions has frequently been tenuous. We conclude that CNS nodules are a rare extraarticular feature of RA which, although often of uncertain clinical significance, should be considered as a possible etiology when neurologic dysfunction occurs in the RA patient.
