Atypical presentation of eosinophilic granulomatosis - typical presentation in an ageing population?

Severe systemic vasculitis presenting in an 80 year old female involving a presentation with recurrent pyrexia, eosinophilia, mononeuritis multiplex against a background of late onset asthma, consistent with eosinophilic vasculitis with angiitis is described. Despite appropriate management with resolution of systemic symptoms, she failed to return to baseline functionality. Systemic vasculitis is rare in this population cohort, but it is important to consider as it is treatable albeit with a guarded outlook for full neurological recovery.
