Rheumatoid arthritis with pachymeningitis - a case presentation and review of the literature

Rheumatoid meningitis (RM) is a rare central nervous system (CNS) manifestation of rheumatoid arthritis (RA) with a wide spectrum of symptoms. We present a review of the literature with a rare illustrative case of a 61-year-old man with a history of seropositive rheumatoid arthritis (RA) who presented headaches, stroke-like symptoms and seizures. MRI revealed the leptomeningeal enhancement in the right hemisphere. As cerebromeningeal fluid showed increased level of protein and was positive for Candida mannan, the initial clinical diagnosis was fungal meningitis. Despite the antifungal treatment the patient's clinical condition did not improve. Detailed laboratory, radiologic and histopathological diagnostics enabled the diagnosis of RM. In conclusion is worth to highlight that presentation of RM is variable and complex, diagnosing it is a big dilemma which is why it must be considered in the differential in a patient with long-standing seropositive RA.
