Pulmonary sequestration (PS) is a condition that may remain asymptomatic and never be diagnosed. Extralobar sequestration (ELS) accounts for 25% of all sequestrations and may present with respiratory distress, feeding difficulties, or congestive heart failure in the first 6 months of life. It is usually identified by routine sonography when screening for other congenital anomalies and may occur in the thoracic cavity or above or below the diaphragm. 2 Go However, it is rarely reported in the mediastinum, especially at the neonatal stage. We now describe an asymptomatic newborn with ELS in the posterior mediastinum.
