"Meandering" pulmonary veins: report of a case in an asymptomatic 12-year-old girl.

We report a case of a healthy, asymptomatic 12-year-old girl in whom anomalous pulmonary venous connection to the left atrium occurred as an isolated congenital anomaly. This condition, termed "meandering" pulmonary veins, is closely related to scimitar syndrome and is usually associated with hypogenesis of the right lung and dextropositioning of the heart. To our knowledge, ours is only the second reported case of meandering pulmonary veins occurring as an isolated anomaly.
