Rheumatoid meningitis (RM) is a rare condition seen in patients with longstanding rheumatoid arthritis (RA). It can present with a variety of neurological symptoms and is often mistaken for other neurological conditions, especially in the setting of immune suppression in these patients. We present a rare case of RM in an elderly woman with RA that presented with focal neurological symptoms and was eventually diagnosed on brain biopsy. Our case serves to highlight the diagnostic dilemmas faced while evaluating and treating patients presenting with such an exceedingly rare condition and the importance of multidisciplinary collaboration in the management of such complex patients.
