Comments

Idiopathic dilation of the main pulmonary artery may occur and be first noted on a screening chest xray without accompanying murmur or physical findings. It is not the result of any shunt and there is no pulmonary valve abnormality or pulmonary hypertension.

The MRI views shown here make clear that the dilation is primarily of the main pulmonary artery segment. Aside from the unusual vessel configuration, the finding is of no clinical consequence.
