Clinical presentation and color doppler findings are suggestive of giant cell arteritis.

Giant cell arteritis (a.k.a Horton disease or temporal arteritis) is the most common primary vasculitis in adults. It typically affects people of more than 50 years of age (median age at diagnosis between 70-75 years old).

The vessels most commonly involved are the superficial temporal artery, the ophthalmic artery, the posterior ciliary arteries, and the vertebral arteries, and less commonly, the aorta, coronary arteries, and carotid circulation.
