Horseshoe lung associated with anomalous pulmonary venous connection without pulmonary hypoplasia

Abstract

SummaryHorseshoe lung is an exceedingly rare congenital malformation, characterized by unilateral pulmonary hypoplasia together with a midline isthmus producing fusion of the tissues of the lower lobes. It is frequently associated with other cardiac and extracardiac anomalies. We report an infant with a variant of the horseshoe lung with partial anomalous venous connection of intracardiac type, ventricular septal defect, and persistent left superior caval vein. There was no pulmonary hypoplasia.
