Although not the most preferred methodology, chest x rays may be used as a diagnostic tool in the evaluation of a partial anomalous pulmonary venous connection. Findings commonly include evidence of increased vascular markings and cardiomegaly.

Cardiomegaly and increased vascular markings may be observed on chest x ray. The main pulmonary artery may be dilated. The mediastinum may be widened due to veins draining from the left lung into the left vertical vein.

There may be evidence of the Scimitar syndrome in which an anomalous vein drains into the inferior vena cava at the level of the diaphragm.

It should be noted that the chest x ray may be normal.
