Intrapericardial bronchogenic duplication cyst.

Bronchogenic cysts arise from an abnormal budding of the ventral diverticulum of the foregut or the tracheobronchial tree, during embryogenesis. Intrapericardial cysts are rare, accounting for 27% of bronchogenic cysts. In this case report, we present a young woman with a symptomatic intrapericardial bronchogenic cyst compressing the superior vena cava. The cyst was resected via median sternotomy, alleviating the patients' preoperative symptoms.
