Learning objectives To describe the imaging findings of congenital and acquired abnormalities of the pulmonary arteries.  To review the imaging techniques used to evaluate these alterations.To discuss the differential diagnosis.
Read more Background When thinking about abnormalities of the pulmonary arteries, pulmonary embolism (PE) is what first comes to mind. Being the third most common cause of cardiovascular death worldwide, PE is not surprisingly one of the most frequent reasons for requesting radiological evaluation. However, there are less frequent alterations, congenital or acquired,  that could present with similar symptoms and radiological findings as PE and radiologists should be familiar with these entities as well. 
Read more Findings and procedure details Abnormalities of the pulmonary arteries can be classified into acquired and congenital. Acquired abnormalities are usually symptomatic and include different entities, among which pulmonary embolism is by far the most frequent. Congenital alterations in adults include left pulmonary artery sling, unilateral proximal interruption of the pulmonary artery and iIdiopathic dilatation of the pulmonary trunk. Although these abnormalities can be symptomatic, they most often present as an incidental finding on imaging. Contrast-enhanced CT is the technique of choice to evaluate most of these entities....
Read more Conclusion When evaluating alterations of the pulmonary arteries, radiologists should think beyond PE. In this exhibit, abnormalities of the pulmonary arteries are reviewed so as to improve radiologists’ familiarity with the key imaging findings that can help them establish an accurate diagnosis.
