CTICasesTakayasu Arteritis with Pulmonary and Subclavian Involvement
Imaging findings
CT angiography in a 20-year-old female with ulcerative colitis shows concentric thickening and narrowing of the right pulmonary artery and severe narrowing of the right axillary and subclavian arteries, without associated aortitis.
Key takeaways
Takayasu arteritis is a large-vessel vasculitis that typically involves the aorta and its main branches. However, it can selectively involve the pulmonary arteries and distal upper extremity arteries, presenting without classic aortitis, particularly in young females.
