Central nervous system (CNS) involvement is extremely rare in patients with rheumatoid arthritis (RA). Additionally, most patients with CNS involvement have chronic and severe RA. We present a report of a 66-year-old man who was diagnosed with rheumatoid meningitis and CNS vasculitis without a history of RA. His initial symptom was seizure. Brain magnetic resonance imaging showed leptomeningeal enhancement.CSF analysis revealed slight increase in the number of white blood cells. An examination of viral markers and culture studies for infectious etiology were unremarkable. However, the rheumatoid factor was positive and the levels of anti-cyclic citrullinated peptide antibody were very high. The patient was diagnosed with rheumatoid meningitis and received steroid therapy. However, he developed CNS vasculitis. We suggested that the possibility of rheumatoid meningitis should be considered during the differential diagnosis stage in patients with uncontrolled meningitis, even though RA does not typically show CNS involvement.

Methotrexate-associated lymphoproliferative disorder (MTX-LPD) with central nervous system (CNS) disorder caused by Epstein-Barr virus (EBV) infection is very rare. We report a case of other iatrogenic immunodeficiency-associated lymphoproliferative disorder (OII-LPD) with EBV meningitis in an 83-year-old woman. She was diagnosed with rheumatoid arthritis and treated with MTX for 10 years.

Rheumatoid meningitis (RM), a rare neurological complication of rheumatoid arthritis (RA), presented as hypertrophic pachymeningitis and leptomeningitis in two octogenarian patients. Case 1 had established RA, while Case 2 was diagnosed with RA after neurological onset. Both patients initially received high doses of corticosteroids.

Crowned Dens Syndrome (CDS) is a rare but important consideration in the differential diagnosis of cervical spine pain in older adults. CDS is characterized by calcium pyrophosphate dihydrate (CPPD) crystal deposition around the odontoid process, often leading to symptoms that overlap with more common conditions such as rheumatoid arthritis (RA), meningitis, or cervical spondylosis. We report the case of a 74-year-old male with chronic neck pain and restricted cervical range of motion.

Rheumatoid meningitis is a rare central neurological complication associated with rheumatoid arthritis. We report an unusual case of rheumatoid meningitis presenting with clinical and radiological findings resembling subarachnoid hemorrhage, with no history of rheumatoid arthritis diagnosis and negative serum rheumatoid factor. A woman in her fifties presented with a severe headache and loss of consciousness.

An 80-year-old woman with sudden generalized convulsions was admitted to our hospital. She had a 33-year history of rheumatoid arthritis. Head magnetic resonance imaging (MRI) at the time of admission showed characteristic leptomeningeal findings, and the anti-cyclic citrullinated peptide antibody (ACPA) titer in the cerebrospinal fluid (CSF) was elevated, thus leading to a diagnosis of rheumatoid meningitis (RM).
