Hyperinflation of the superficial temporal artery is a painful nodule with a reddened surface or a nodule-like artery that can sometimes be palpated locally in the presence of painful giant cell arteritis. Giant cell arteritis, also known as temporal arteritis. So, how should the differential diagnosis of a violently distended superficial temporal artery be made? A biopsy of a hyperinflated temporal artery shows vasculitis, an infiltrate of predominantly mononuclear cells, or granulomatous inflammation, and often with multinucleated giant cells. Arterial biopsy of the superficial temporal artery or occipital artery is the most reliable means of confirming the diagnosis of hyperinflation of the superficial temporal artery. The positivity rate of superficial temporal artery biopsy is between 40 and 80%, with 100% specificity. Since the lesions of the superficial temporal artery A are segmental and jumpy, biopsy should be taken for several centimeters in length to the site of tenderness or nodularity, and serial pathological sections should be made to improve the detection rate. Temporal artery biopsy is safer, and a negative biopsy on one side can be done on the other side or choose occipital artery biopsy. 2.Temporal arteriogram is valuable for the diagnosis of superficial temporal artery with swelling, and can detect irregularities and stenosis of the temporal artery lumen and other changes. 3.Selective arteriogram can be done when there is suspected involvement of large arteries, such as aortic arch and its branch arteriogram.
