Multilevel Thrombosed Aneurysms in Takayasu Arteritis: The Critical Role of CT Angiography

Abstract: Takayasu arteritis is a rare large-vessel vasculitis affecting the aorta and its major branches, primarily in young women. Although stenotic lesions are typical, aneurysmal complications may occur and significantly increase the risk of morbidity and mortality. We present the case of a 30-year-old male patient followed for Takayasu disease who underwent thoracoabdominopelvic CT angiography as part of therapeutic planning. The scan revealed multiple aneurysmal dilations, including a thrombosed aneurysm of the brachiocephalic trunk, the left subclavian artery, and the subrenal abdominal aorta, associated with signs suggestive of impending rupture. Diffuse mural thickening of the supra-aortic trunks indicated chronic arterial inflammation. This case highlights the value of cross-sectional imaging in the comprehensive evaluation of Takayasu arteritis and the urgent need for appropriate vascular intervention in high-risk presentations.
