Abstract:
Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare condition of systemic vasculitis of small to medium-sized blood vessels. We herein report the case of a 75-year-old man who presented with hemiplegia on his right side due to cerebral infarction following myalgia and a high fever. He had no history of asthma or allergic rhinitis. He was diagnosed with EGPA based on the presence of eosinophilia, sinusitis suggested by magnetic resonance imaging, and muscle pathology. His hemiplegia improved rapidly after corticosteroid therapy. This case suggests that EGPA should be a differential diagnosis of cerebral infarction with myalgia and eosinophilia.
Insights
Eosinophilic granulomatosis with polyangiitis (EGPA), a rare vasculitis, can cause stroke. This case highlights EGPA as a potential cause of cerebral infarction in patients with fever, myalgia, and eosinophilia.
Area of Science:
- Rheumatology
- Neurology
- Pathology
Background:
- Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis affecting small to medium-sized blood vessels.
- EGPA typically presents with asthma, allergic rhinitis, and eosinophilia, but atypical presentations occur.
Observation:
- A 75-year-old man presented with right-sided hemiplegia and cerebral infarction.
- His symptoms included myalgia and high fever, with no prior history of asthma or allergic rhinitis.
- Diagnostic findings included eosinophilia, sinusitis on MRI, and characteristic muscle pathology.
Findings:
- The patient was diagnosed with Eosinophilic granulomatosis with polyangiitis (EGPA).
- Rapid improvement in hemiplegia was observed following corticosteroid treatment.
Implications:
- This case underscores the importance of considering EGPA in the differential diagnosis of cerebral infarction, particularly in patients presenting with myalgia and eosinophilia.
- Early recognition and treatment of EGPA can lead to favorable neurological outcomes.
