Answer:
Takayasu’s arteritis.
Findings:
Imaging depicts circumferential mural wall thickening of bilateral CCA, Brachiocephalic artery, thoracic aorta, pulmonary arties and suprarenal abdominal aorta consistent with early systemic phase of Takayasu’s arteritis.
Discussion:
Takayasu’s arteritis (TA) is clinically classified as a large-vessel vasculitis, as it largely affects the aorta and its major branches and the pulmonary arteries. TA is a disease of young patients. Typical imaging findings include arterial wall thickening early in the disease, followed by stenosis, occlusion, and aneurysmal dilatation in the late phase
The most commonly involved vessels are the proximal subclavian and carotid arteries .The pulmonary arteries are affected in approximately 50–80% of cases and may demonstrate mural calcification late in the disease. The lesions of TA are positive on FDG-PET, but the utility of PET in monitoring disease activity has yet to be conclusively proven.
