Giant cell arteritis (GCA), also called temporal arteritis, is an inflammatory autoimmune disease of large blood vessels. [ 4 ] [ 7 ] Symptoms may include headache , pain over the temples, flu-like symptoms , double vision , and difficulty opening the mouth. [ 3 ]
The halo sign of temporal arteritis should not be confused with Deuel's halo sign, which is a sign of fetal death. [3] The halo sign is also understood as a region of ground-glass attenuation surrounding a pulmonary nodule on an X-ray computed tomography (CT scan) of the chest.
Histiocytes, giant cells [5] Giant cell arteritis, also often called temporal arteritis (although they differ slightly) Superficial temporal artery, other medium- and large-sized vessels, [6] e.g. those supplying the head, eyes and optic nerves: Lymphocytes, macrophages, and multinucleated giant cells [6] Polyarteritis nodosa
The finding were that CT scan was a reliable means to diagnose IAA. [5] 2008 a study was done to test the effectiveness of MRI and FDG-PET tests to detect, diagnose, and measure inflammatory aortic arch syndrome. The results from the study were that MRI and FDG-PET were unreliable techniques due to giant-cell arteritis. [6]
Individuals diagnosed with giant cell arteritis may present with superficial temporal artery stenosis, occlusion, or halo sign (a dark patch surrounding the artery due to vessel wall edema). [23] When diagnosing patients with granulomatosis with polyangiitis, computed tomography is useful.
AAION is due to temporal arteritis (also called giant-cell arteritis), an inflammatory disease of medium-sized blood vessels (Chapel-Hill-Conference) that occurs especially with advancing age. In contrast, NAION results from the coincidence of cardiovascular risk factors in a patient with "crowded" optic discs.
Sudden visual loss is the most common symptom in AAION, [1] and is most often accompanied by other symptoms of temporal arteritis: such as jaw claudication, scalp tenderness, unintentional weight loss, fatigue, myalgias and loss of appetite. [1] A related disease called polymyalgia rheumatica has a 15 percent incidence of giant cell arteritis.
Severe vasculitis of the major vessels, displayed on FDG-PET/CT Laboratory tests of blood or body fluids are performed for patients with active vasculitis. Their results will generally show signs of inflammation in the body, such as increased erythrocyte sedimentation rate (ESR), elevated C-reactive protein (CRP), anemia , increased white blood ...
