Systemic lupus erythematosus in a patient with multiple system atrophy: A case report.

Rationale: Multiple system atrophy is a late-onset rare neurodegenerative movement disorder which results in debilitating disease. Fever frequently ensues in the context of infections which can be associated with significant morbidity and mortality, but among alternative diagnostic possibilities neoplasms and autoimmune disorders should be considered.

Patient Concerns: We describe a case of a prolonged febrile syndrome in a 55-year-old female patient with onset of multiple system atrophy two years before presentation.
