Meandering right pulmonary vein associated with severe and progressive "idiopathic-like" pulmonary hypertensive vascular disease.

Congenital anomalies of the pulmonary veins are rare. Meandering right pulmonary vein, considered a part of the Scimitar syndrome spectrum, is often an incidental finding during chest imaging. We present the case of a 4-year-old girl diagnosed with meandering pulmonary vein, who developed pulmonary hypertensive disease with an aggressive course, in spite of absence of hypoxia or elevated pulmonary wedge pressure.
