A rare intrapericardial bronchogenic cyst was found incidentally in a child during surgery for an atrial septal defect. Complete resection of the cyst was successful, with an uneventful recovery, highlighting a unique pediatric cardiac surgical finding.
Area of Science:
- Cardiology
- Thoracic Surgery
- Pediatric Surgery
Background:
- Intrapericardial bronchogenic cysts are rare congenital anomalies.
- Surgical repair of sinus venosus atrial septal defects with partial anomalous pulmonary venous return is a standard pediatric cardiac procedure.
Observation:
- A 3-year-old child presented for elective repair of a sinus venosus atrial septal defect with partial anomalous pulmonary venous return.
- An incidental finding during surgery was a cystic mass overlying the pulmonary artery within the pericardium.
Findings:
- The cystic mass was resected and diagnosed as an intrapericardial bronchogenic cyst.
- Histological examination revealed respiratory mucosa, cartilage, and smooth muscle, confirming the diagnosis.
- The cyst was completely removed, and the patient experienced an uneventful postoperative recovery.
Implications:
- This case highlights the importance of intraoperative awareness for incidental findings during cardiac surgery.
- Complete resection of intrapericardial bronchogenic cysts ensures favorable outcomes.
- Management of these rare cysts may require a multidisciplinary approach involving cardiac and thoracic surgeons.
