Giant cell aortitis and Noonan Syndrome

Connective tissue abnormalities leading to aortic root dilatation and the sinuses of Valsalva aneurysm have been reported in Noonan syndrome. This report is the first description of giant cell aortitis in Noonan syndrome and may provide a link between aortic aneurysm, and giant cell granuloma of bone in Noonan syndrome.
