| 1 | Pericardial effusion with tamponade – an uncommon presentation leading to the diagnosis of eosinophilic granulomatosis polyangiitis: A case report显示文摘BACKGROUND Eosinophilic granulomatosis polyangiitis(EGPA)is a small vessel necrotizing vasculitis that commonly presents as peripheral eosinophilia and asthma;however,it can rarely manifest with cardiac involvement such as pericarditis and cardiac tamponade.Isolated pericardial tamponade presenting as the initial symptom of EGPA is exceedingly rare.Early diagnosis and appropriate treatment are crucial to prevent life-threatening outcomes.CASE SUMMARY 52-year-old woman with no past medical history presented with progressive dyspnea and dry cough.On physical exam she had a pericardial friction rub and bilateral rales.Vital signs were notable for tachycardia at 119 beats per minute and hypoxia with 89%oxygen saturation.On laboratory exam,she had 45%peripheral eosinophilia,troponin elevation of 1.1 ng/mL and N-terminal prohormone of brain natriuretic peptide of 2101 pg/mL.TTE confirmed a large pericardial effusion and tamponade physiology.She underwent urgent pericardial window procedure.Pericardial and lung biopsy demonstrated eosinophilic infiltration.Based on the American College of Radiology guidelines,the patient was diagnosed with EGPA which manifested in its rare form of cardiac tamponade.She was treated with steroid taper and mepolizumab.CONCLUSION This case highlights that when isolated pericardial involvement occurs in EGPA,diagnosis is recognized by performing pericardial biopsy demonstrating histopathologic evidence of eosinophilic infiltration. | Loba Alam Glenmore Lasam Robert Fishberg | 2020 | World Journal of Cardiology2020，12，9： | 0 |
