Comments

Scimitar syndrome, also known as pulmonary venolobar syndrome or hypogenetic lung syndrome, is a malformation classically characterized by the association of hypoplasia of the right lung with anomalous pulmonary venous return (usually partial) of this lung. This anomalous vein has vertical orientation, usually draining towards the inferior cava vein (supra- or infra-diaphragmatic), and its shape resembles a scimitar. There may also be collateral aortopulmonary arteries in this syndrome, which may cause pulmonary hypertension. Up to one-third of all cases also present congenital cardiac anomalies, such as ventricular or atrial septum defect, patent arterial duct, coarctation of the aorta and tetralogy of Fallot. In the case shown herein, the patient was asymptomatic, and this diagnosis was a test finding.
