POS0815- Differences in giant cell arteritis manifestations according to the ultrasound pattern of disease involvement

Giant cell arteritis (GCA) is the most common form of primary systemic vasculitis in patients aged >50 years. It predominantly affects the cranial arteries; however, extra-cranial disease involving the aorta and its major branches, known as large-vessel GCA (LV-GCA), can be present in 20-80% of cases, depending on the imaging modality used for screening the disease.
