A temporal artery biopsy (TAB) can be performed to differentiate between the two disease states. [13] As the disease progresses, the arteriosclerosis results in the obstruction of normal blood flow, and potentially the formation of blood clots.
The temporal area may be tender. [21] Decreased pulses may be found throughout the body [21] Evidence of ischemia may be noted on fundal exam. [21] Bruits may be heard over the subclavian and axillary arteries [21] Intermediate magnification micrograph showing giant cell arteritis in a temporal artery biopsy. The arterial lumen is seen on the left.
The current highest standard for diagnosis is a temporal artery biopsy. [12] The skin on the patient's face is anesthetized, and an incision is made in the face around the area of the temples to obtain a sample of the temporal artery. The incision is then sutured.
The parietal branch of the superficial temporal artery (posterior temporal) is a small artery in the head.It is larger than the frontal branch and curves upward and backward on the side of the head, lying superficial to the temporal fascia; it joins with its fellow of the opposite side, and with the posterior auricular and occipital arteries.
About 15% of people who are diagnosed with polymyalgia rheumatica also have temporal arteritis, and about 50% of people with temporal arteritis have polymyalgia rheumatica. Some symptoms of temporal arteritis include headaches , scalp tenderness, jaw or facial soreness, distorted vision , or aching in the limbs caused by decreased blood flow ...
The most definitive diagnostic modality is a biopsy of the affected blood vessel however brain biopsy has a low yield, with up to 30-50% of biopsies being normal in suspected cases. [5] This is due to some cases having an irregular distribution of vessel involvement (making biopsy technically difficult) or larger vessels being unable to be ...
Giant-cell arteritis (GCA) / Temporal arteritis – Affects medium- & large-sized vessels of the head, typically branches of the external carotid artery and namely the temporal artery. Occlusion of the ophthalmic artery results in blindness. Suspicion of GCA necessitates immediate treatment with glucocorticoids and temporal artery biopsy.
In cases where symptoms suspicious of giant cell arteritis (GCA) are present, but a temporal artery biopsy reveals fibrinoid necrosis in small vessels branching from the temporal artery, and the absence of the typical GCA histological features, this discrepancy may suggest an alternative diagnosis, as the occurrence of fibrinoid necrosis in GCA ...
