Pathology - Temporal Arteritis
Pathophysiology
Giant cell arteritis (GCA) is another name for temporal arteritis.
Temporal artery disease is a common symptom of systemic vasculitis, or GCA. Moreover, polymyalgia rheumatica, which affects the hips and shoulders, is closely linked to it. This disease causes inflammation in the arteries, which may lead to distal ischemia. It is possible for other carotid branches to become involved as well; blindness may result from ocular artery irritation.
Consequently, it's critical to start high-dose steroid treatment right away. Intravenous steroids may be beneficial if the patient has visual impairment. If the sample is obtained within a few days of the start of treatment, the use of steroids has no effect on the results of the biopsy.
Biopsies reveal big cells and granulomatous alterations, although a negative biopsy does not always rule out a diagnosis of GCA. This is because the regions collected during the biopsy may not contain the areas of inflammation, and the inflammation manifests themselves as skip lesions.
