Abstract
A 55-year-old woman with a history of allergic sinusitis was being administered cyclosporine for ptosis and diplopia due to myasthenia gravis since age 46 years. She developed painful dysesthesia that began in her feet and later spread to her palms, leading to difficulty in walking. Eosinophils were markedly increased in the peripheral blood. Nerve conduction studies revealed mononeuritis multiplex. Nerve biopsy showed the infiltration of eosinophils in the superior neurovasculature. Based on these findings, eosinophilic granulomatous polyangiitis was diagnosed. Methylprednisolone pulse therapy was followed by oral prednisolone. Two weeks after treatment, the patient could do normal daily activities without assistance. In patients with myasthenia gravis having a history of allergic diseases, considering EGPA as a complication and monitoring prior changes in blood data are necessary for early detection before apparent tissue damage.
期刊介绍：
This new peer-reviewed online-only journal publishes original case reports covering the entire spectrum of neurology. Clinicians and researchers are given a tool to disseminate their personal experience to a wider public as well as to review interesting cases encountered by colleagues all over the world. To complement the contributions supplementary material is welcomed. The reports are searchable according to the key words supplied by the authors; it will thus be possible to search across the entire growing collection of case reports with universally used terms, further facilitating the retrieval of specific information. Following the open access principle, the entire contents can be retrieved at no charge, guaranteeing easy access to this valuable source of anecdotal information at all times.
