Abstract

We describe a man presenting with unusual neurological manifestations of systemic lupus erythematosus (SLE) including pachymeningitis, aseptic meningitis and encephalitis with grossly elevated cerebrospinal fluid protein, responding to immunosuppression. Initially he had intermittent dysarthria, dysphasia and unilateral upper limb weakness. One month later he experienced dysphasia, right-sided hemiparesis and confusion. Cerebrospinal fluid (CSF) analysis showed a white cell count of 70 x 106/litre and an unusually elevated protein level of 5.39 g/litre. An MRI brain showed dural and leptomeningeal enhancement compatible with a meningitic process. He improved with cefotaxime and aciclovir. On day seven of antimicrobials he developed left-sided weakness, sensory inattention and a left homonymous hemianopia. He responded well to intravenous methylprednisolone. On switching to oral prednisolone he developed expressive dysphasia, a right inferior quadrantanopia and seizures. His bloods were suggestive of macrophage activation syndrome. The patient improved with methylprednisolone and intravenous immunoglobulins, and the improvement was sustained on switching back to oral prednisolone. The prevalence of neuropsychiatric manifestations of SLE varies between 14 and 80% and according to the American College of Rheumatology includes 19 conditions. This case is unique because although some features were in keeping with aseptic meningitis the MRI appearances were also suggestive of pachymeningitis.
