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

## TL;DR

A 52-year-old woman presented with neurological and skin symptoms, leading to a diagnosis of EGPA, a rare vasculitis that can mimic other conditions.

## Contribution

This case highlights the diagnostic challenges of EGPA due to its varied clinical manifestations.

## Key findings

- EGPA was diagnosed in a patient presenting with purpura, mononeuritis multiplex, and cerebral infarction.
- Treatment with glucocorticoids and cyclophosphamide led to rapid clinical remission.
- The case underscores the importance of reviewing past medical history for accurate diagnosis.

## 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.
