CTICasesTakayasu Arteritis
Imaging findings
CT chest shows circumferential, dense calcification and ossification of the wall of the entire ascending aorta, arch, and arch vessels, extending to the pulmonary artery. The patient has a history of retroperitoneal fibrosis.
Key takeaways
Takayasu arteritis is a large-vessel vasculitis. In the chronic 'burnout' phase, the inflamed aortic wall undergoes extensive calcification and ossification, mimicking severe atherosclerosis but typically showing a smooth, circumferential distribution and extending into the branch vessels.
