| Sumario: | ABSTRACT Rheumatoid meningitis (RM) is a rare complication of rheumatoid arthritis (RA). RM mimics many other conditions such as subdural empyema, unsteady gait, focal brain dysfunction, stroke, relapsing-remitting motor signs, headache, neuropsychiatric disorders, seizures, parkinsonism, and meningeal tumors. RM is considered a disease with poor prognosis. However, cases reported in the last decade show a good outcome. We report two cases with a favorable outcome. A 48-year-old man with a three-year history of RA admitted for headache, sensory disturbances, and speech difficulties. Brain magnetic resonance imaging (MRI) showed a left parietal subdural laminar lesion with restricted diffusion and a small left superior frontal acute infarction. A subdural empyema was originally suspected, and antimicrobials were prescribed. A follow-up MRI did not show progression of the subdural lesion and the patient was discharged 14 days after admission without focal deficits. A 44-year-old female patient with two years of seronegative RA was admitted for severe headache, confusion, nausea and vomiting. Brain MRI showed subtle supra and infratentorial leptomeningeal involvement and a left cerebellar acute infarct. A meningoencephalitis due to etanercept was initially thought and treated with dexamethasone. The patient was discharged but had to be admitted again and a new MRI showed a progression of the leptomeningeal involvement. She worsened and required endotracheal intubation. Cyclophosphamide was started and the patient became asymptomatic three months later. We propose that treatment should not be delayed waiting a biopsy when a diagnosis of RM is made and after a cerebrospinal fluid infection has been ruled out. |
