Kermani TA, et al. - Authors assessed the large-vessel (LV) abnormalities on serial imaging in patients with giant cell arteritis (GCA) and discern predictors of new lesions. On first imaging, LV abnormalities were common in this cohort of patients with GCA. In patients with arterial abnormalities, development of new arterial lesions occurred in patients with arterial abnormalities at first imaging, often in the absence of symptoms of active disease. A consideration to arterial imaging in all patients with GCA at diagnosis and serial imaging at least in patients with baseline abnormalities was suggested.
