Imaging of pulmonary venous developmental anomalies.

OBJECTIVE: The purpose of this article is to review pulmonary venous embryology and to present the imaging findings of a variety of pulmonary venous developmental anomalies, including total anomalous pulmonary venous connection, partial anomalous pulmonary venous connection, pulmonary vein stenosis and hypoplasia/atresia, and cor triatriatum.

CONCLUSION: There are numerous developmental pulmonary venous anomalies. Although these conditions have traditionally been evaluated with echocardiography and angiography, they can be accurately diagnosed using both MRI and MDCT.
