Which of the following is NOT associated with Giant Cell Arteritis?

• A. Jaw claudication
• B. Amaurosis fugax
• C. Pulsatile tinnitus
• D. Neck pain

Answer: (C)

Giant cell arteritis is a large-vessel vasculitis that inflames arteries of the head, leading to ischemic symptoms rather than sound-related ones. The inflammation can cause jaw claudication when chewing becomes painful due to reduced blood flow to the masticatory muscles, and amaurosis fugax as transient vision loss from ophthalmic/retinal ischemia. Neck pain can appear as part of the head-and-neck vascular involvement or from scalp tenderness. Pulsatile tinnitus, on the other hand, results from turbulent blood flow audible in the ear due to vascular or middle/inner ear pathology, and it is not a typical feature of giant cell arteritis. So pulsatile tinnitus is not associated with this condition.
