A case of hypereosinophilic syndrome with pleural effusion and pulmonary embolism / 천식및알레르기

Hypereosinophilic syndrome is characterized by prolonged eosinophilia of blood and bone marrow and eosinophil-related tissue damage to variable organs without an identifiable underlying cause. We report a case of hypereosinophilic syndrome with pleural effusion and pulmonary embolism in a 29-year-old man. Chest CT and lung perfusion scan demonstrated multiple segmental perfusion defects in both lungs. After intravenous injection of methyl-prednisone for 3 weeks, blood eosinophil count and pulmonary lesions were normalized.
