What observation is made regarding the temporal artery in patients with Giant Cell Arteritis?

In patients with Giant Cell Arteritis, the temporal artery typically appears enlarged. This condition involves inflammation of the large and medium-sized blood vessels, most commonly affecting the temporal arteries. Patients often present with headaches, scalp tenderness, and sometimes visual disturbances, which are all indicative of the underlying vascular compromise. An enlarged temporal artery can often be palpated or visualized during examination and is a significant clinical marker that prompts further evaluation.

The enlargement is due to the inflammation and subsequent thickening of the arterial wall, which can lead to ischemic complications if not treated promptly. Recognizing this feature is crucial for timely intervention, as untreated Giant Cell Arteritis can result in severe consequences, including permanent vision loss.

While the temporal artery may sometimes show signs of shrinkage due to inflammation or may appear normal in some cases, the characteristic enlargement is a hallmark of the disease that healthcare providers look for during an examination.
