Intra-Alveolar Hemorrhage Revealing Eosinophilic Granulomatosis with Polyangiitis (EGPA)

Eosinophilic Granulomatosis with Polyangiitis (EGPA) is a rare systemic vasculitis that combines severe or late-onset asthma with cardiac, ear-nose-throat (ENT), neurological, or renal manifestations. Asthma, as one of the most common features of EGPA, plays a central role in the disease's progression. Intra-alveolar hemorrhage, on the other hand, is a potentially serious but rare complication. We report a case of EGPA diagnosed due to intra-alveolar hemorrhage associated with an acute asthma exacerbation and systemic manifestations in a 58-year-old patient. This case allows discussion of the diagnostic and therapeutic challenges and the prognosis of this rare and severe condition.
