Answer for BIR CoW 18 March 2018
Aortic Pseudoanuerysm
Findings
6x5x5 cm smooth walled sac arising from the anterior wall of ascending aorta through a communication of 1.6 cm with surrounding haematoma.It displaces the great vessels posteriorly and also compresses the right pulmonary artery.
Discussion
False aneurysm also known as pseudoaneurysm is a breach in the vessel wall such that the blood leaks through the wall but is contained byadventitia or surrounding perivascular soft tissue.Common causes are trauma,iatrogenic,mycotic aneurysm,penetrating atherosclerotic ulcer myocardial infarction,vessel wall injury / erosion by tumor ,vasculitis etc.Ultrasound may show characteristic yin-yang sign due to to and fro pattern of flow. Ct shows contrast enhanced smooth walled sac from a vessel through a communication.
