Severe Mononeuritis Multiplex in Eosinophilic Granulomatous Polyangiitis: A Case Report

This report describes a 48-year-old man who presented with a month history of weakness and paraesthesiaassociated with severe pain of all four limbs. Initially diagnosed and treated as Guillain Barre syndrome dueto the severity of his extremity weakness, it was later discovered to be eosinophilic granulomatouspolyangiitis (EGPA). Mononeuritis multiplex should not be underestimated or overlooked in the setting of diagnosing EGPA andrequires prompt treatment with biologics to limit the permanent consequences on patient's quality of lifewith regard to developing limb weakness and pain. Although peripheral neuropathy, namely, mononeuritis multiplex, is not the most common feature of EGPA,it is important to consider it in order not to delay treatment with biologic agents that as seen in our patientcan both halt the progress of the disease as well as give the patient a better quality of life
