Abstract:
We describe a case of a 3-year-old child with an intrapericardial bronchogenic cyst arising from the pericardium overlying the pulmonary artery found incidentally at the time of elective repair of a sinus venosus atrial septal defect with partial anomalous pulmonary venous return. A cystic mass overriding the right pulmonary artery was resected and diagnostic studies revealed multiple loculated cysts lined by respiratory mucosa with cartilage and smooth muscle in the wall consistent with a bronchogenic cyst. The cyst was completely resected and postoperative recovery was uneventful.
