Brachiocephalic artery pseudotumor
Imaging findings
Chest radiographs show a right-sided upper mediastinal mass-like opacity. Chest CT demonstrates an extremely tortuous, buckled right brachiocephalic artery, which is border-forming on the mediastinum, in the setting of an elongated, elevated aortic arch.
Key takeaways
A tortuous brachiocephalic artery can buckle and simulate a lung or mediastinal tumor on chest radiographs, particularly in elderly patients with elevated aortic arches. CT angiography is diagnostic and prevents unnecessary biopsy.
