Abstract

|
Pulmonary sequestration is a developmental anomaly of broncho-pulmonary foregut with nonfunctioning parenchymal tissue, which usually supplied by systemic circulation. Pulmonary sequestration is detected by ultrasonography as a homogeneous echogenic mass and also by Doppler blood flow from systemic circulation to the mass. Pulmonary sequestration is classified into intralobar type and extralobar type. Extralobar type accounts for only 15~25% of the cases and it is subdivided into intrathoracic forms, which are most commonly found and extrathoracic type, which includes intraabdominal, retroperitoneal, or mediastinal masses. We report a rare case of prenatal detection of mediastinal mass with a brief review of literatures, which was confirmed to be a pulmonary sequestration by surgical mass excision after birth.
