Rheumatoid meningitis.

Rheumatoid meningitis is a rare, potentially treatable condition that can mimic a wide range of neurological conditions, including vascular syndromes and encephalopathies. Despite a concurrent history of rheumatoid arthritis, patients often have no active synovitis. Here we describe a patient with rheumatoid meningitis who presented to a hyperacute stroke unit with dysarthria on waking and transient facial droop. Published by the BMJ Publishing Group Limited.
