Encephalic large arteries narrowness and peripheral neuropathy in a patient with adult-onset Still’s disease

Abstract

Adult-onset Still's disease (AOSD) is a rare, systemic inflammatory disorder, characterized by spiking high fever, fever-associated evanescent rash, arthritis, myalgia, serositis and hepatosplenomegaly. White blood cell count, neutrophilic cell count, and serum ferritin level are markedly elevated in the active stage of the disease. Neurological complications of AOSD commonly were cranial nerve palsies, seizures, aseptic meningoencephalitis, peripheral neuropathy and Miller-Fisher syndrome. We report a previously healthy 60-year-old Chinese man who fulfilled the criteria for AOSD and had a combination of focal and peripheral neurological symptoms. Magnetic resonance angiography (MRA) and transcranial Doppler ultrasonography (TCD) showed narrowness of cerebral blood vessel. Peripheral neuropathy was confirmed by electromyography and sural nerve biopsy. His generalized neuropathy and other symptoms were rapidly improved by receiving glucocorticoid therapy. We do a literature review about neurological manifestations observed in AOSD patients.
