CTICasesWilliams Syndrome with Supravalvular Aortic Stenosis and Pulmonary Artery Narrowing
▶ Watch on YouTube — age-restricted, cannot embed here
Imaging findings
Diffuse narrowing of the entire supravalvular aorta from the sinotubular junction, measuring approximately 6-7 mm throughout, without normal tapering. Associated relatively mild narrowing of the right pulmonary artery, while the left pulmonary artery was normal.
Key takeaways
This is a genetically confirmed case of Williams syndrome, which is associated with diffuse supravalvular aortic stenosis and can involve pulmonary artery narrowing. While often suspected, true positive cases are relatively uncommon to encounter.
