Acute Respiratory Failure With Hemoptysis in a Teenager Due to Cystic Echinococcosis

Abstract A previously healthy 14-year-old male presented with abrupt onset respiratory failure with hemoptysis and anaphylaxis. Imaging demonstrated a large, cystic lesion with bronchopleural fistula that was consistent with cystic echinococcosis. He underwent thoracotomy for cyst removal and bronchopleural fistula repair, then completed 3 months of albendazole therapy. He developed recurrence of a bronchopleural fistula 4 months after surgery which improved over time with conservative management. This case highlights pathognomonic imaging and pathology findings for cystic echinococcosis.
