Scimitar syndrome.

Scimitar syndrome or congenital pulmonary venolobar syndrome is a rare anomaly most commonly consisting of partial pulmonary venous drainage into the hepatic portion of the inferior vena cava, right lung hypoplasia, dextroposition of the heart, and anomalous systemic arterial supply from aorta or one of its branches to the right lung. We report a four-year-old girl with recurrent pneumonia and failure to thrive, who was diagnosed as having scimitar syndrome.
