Takayasu arteritis (TA) is a chronic large-vessel vasculitis predominantly affecting the aorta and its primary branches. We report three patients with atypical imaging findings diagnosed using computed tomography angiography (CTA). Case 1 (a twenty-five-year-old woman) had diffuse aortic wall thickening with an infrarenal abdominal aortic aneurysm. Case 2 (a thirty-five-year-old woman) showed bilateral renal artery stenosis with left renal arteriovenous fistula. Case 3 (a thirty-eight-year-old woman) demonstrated extensive arterial calcifications, left carotid artery occlusion, and an infrarenal saccular aneurysm. CTA was invaluable in detecting wall thickening, stenosis, aneurysm formation, and calcification. These cases illustrate that atypical vascular involvement may occur in TA and emphasize the role of CTA in comprehensive disease evaluation and management. Early recognition of such atypical radiological features can guide timely management and prevent complications.
