Leptomeningitis in rheumatoid arthritis

Area of Science:

• Neurology
• Rheumatology
• Immunology

Background:

• Rheumatoid meningitis is a known complication of rheumatoid arthritis.
• Rheumatoid leptomeningitis, specifically without pachymeningitis, is exceptionally rare.
• Existing literature on this specific condition is limited.

Purpose of the Study:

• To report a unique case of rheumatoid leptomeningitis.
• To characterize the clinical and radiological features of this rare condition.
• To contribute to the scarce literature on rheumatoid leptomeningitis.

Main Methods:

• Case report methodology.
• Clinical diagnosis based on symptoms and response to treatment.
• Exclusion of other potential causes of meningitis.
• Radiological assessment of leptomeningeal involvement.

Main Results:

• A presumptive diagnosis of rheumatoid leptomeningitis was established.
• The patient showed a clinical response to antirheumatic medications.
• The case presented distinct clinical and radiological findings.

Conclusions:

• Rheumatoid leptomeningitis is a rare but significant neurological complication in rheumatoid arthritis.
• This case expands understanding of its presentation.
• Further research is warranted to fully elucidate this condition.
