Background: This report describes a 48-year-old man who presented with a month history of weakness and paraesthesia associated with severe pain of all four limbs. Initially diagnosed and treated as GBS due to the severity of his extremity weakness, later discovered to be EPGA Objective: Mononeuritis multiplex should not be underestimated or overlooked in the setting of diagnosing EGPA and requires prompt treatment with biologics to limit the permanent consequences on patient’s quality of life in regards to developing limb weakness and pain. Conclusion: Although peripheral neuropathy and 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 patient can both halt the progress of the disease as well as give the patient a better quality of life.
