Eosinophilic Granulomatosis With Polyangiitis Presenting With Purpura, Mononeuritis Multiplex, and Cerebral Infarction.

ABSTRACT

We present a case of a 52-year-old woman who had transient speech impediment and progressive numbness, weakness, and a purpuric rash affecting her limbs, with severe joint pains. Because she had a chest infection two weeks prior, her clinical presentation gave rise to a suspicion of post-infective vasculitis or post-infective polyneuritis. Further investigation proved this to be eosinophilic granulomatosis with polyangiitis (EGPA) presenting with purpura, mononeuritis multiplex, and cerebral infarction. Treatment with glucocorticoids and cyclophosphamide led to rapid remission. This case highlights the potential difficulty in diagnosing EGPA because of its multiple clinical manifestations and emphasizes the importance of a thorough review of the past medical history.
