There is aneurysmal dilatation of the right bronchial artery just inferior to the carina. More distally, there is another smaller segment of aneurysmal dilatation.
The left superior bronchial artery arising from the medial aortic arch is also prominent without focal aneurysmal dilatation. The pulmonary arteries are unremarkable and there is no pulmonary embolism identified. No pulmonary arteriovenous malformation.
Atheromatous calcification of the aortic arch and mural thickening of the proximal left subclavian artery.
No specific cause (e.g. pulmonary arteriovenous malformation or mediastinal malignancy) was identified on this CT. Other common causes include trauma (further history not available).
