Click 28-year-old male with rupture of aberrant left subclavian artery in a right sided aortic arch forming a huge pseudoaneurysm. Contrast enhanced CT of the neck and chest. Axial cuts. Images show a huge pseudoaneurysm measuring 18x7x4 cm in size which is arising from 1.7 cm defect in the aortic wall at the origin of the aberrant left subclavian artery and extending superiorly to the neck and inferiorly to the level of the carina. Left common carotid artery, right common carotid artery and right subclavian artery are seen. Mediastinal hematoma, pneumomediastinum and a left hemothorax causing mediastinal shift, can also be noted in these images. Spiral CT scanner; 1 mm slice. KVP 120, exposure 200. Intravenous contrast 70 ml Omnipaque 300 mg/100 ml.

Images show a huge pseudoaneurysm measuring 18x7x4 cm in size which is arising from 1.7 cm defect in the aortic wall at the origin of the aberrant left subclavian artery (last branch), extending superiorly to the neck and inferiorly to the level of the carina. Left common carotid artery (first branch), right common carotid artery (second branch) and right subclavian artery (third branch) are seen. Pneumomediastinum and mediastinal hematoma can also be noted in these images. Spiral CT scanner; 1 mm slice. KVP 120, exposure 200. Intravenous contrast 70 ml Omnipaque 300 mg/100 ml.

Click 28-year-old male with rupture of the aberrant left subclavian artery in a right sided aortic arch forming a huge pseudoaneurysm. CT arteriography of the neck and chest. Volume rendered three-dimensional image shows a huge pseudoaneurysm arising from the distal part of the aortic arch at the base of the aberrant left subclavian artery. Only the proximal part the left common carotid artery, which was originating as the first branch from the aortic arch, is visible in in this image as this vessel is passing obliquely to the left side. The right common carotid artery and the right subclavian artery are also seen. Multi slice 16 CT scanner, axial 0.6 mm slice. Intravenous contrast 90 ml Omnipaque 300 mg/100 ml. KVP 120, exposure 200
