A Diagnostic Challenge Presenting As Non Resolving Pneumonia In A Young Female

This case highlights the diagnostic challenge of a 35-year-old female initially managed as community-acquired pneumonia, who later presented with persistent respiratory symptoms, systemic complaints, and peripheral blood eosinophilia. Further investigations revealed positive peripheral antineutrophil cytoplasmic antibodies ( p-ANCA )and pulmonary infiltrates, leading to a diagnosis of Eosinophilic Granulomatosis with Polyangiitis (EGPA), a rare form of ANCA-associated vasculitis. She was managed successfully with high-dose methylprednisolone, methotrexate, and supportive care. Our case illustrates the importance of suspecting rare causes in case of non resolving pneumonia.
