Although having a heterogeneous clinical spectrum, the major features of AOSD include fever, rash, and arthritis or arthralgia. Neurological involvement is rare in AOSD with aseptic meningitis being the most common presentation. Guillain-Barre syndrome (GBS) has never been reported as an early presentation of AOSD.
