Abstract
Sir, giant cell arteritis (GCA) commonly involves the cranial arteries in a segmental pattern [1–3]. In the majority of cases, the affection of the temporal arteries can be demonstrated by duplex ultrasonography [4] and is confirmed by biopsy. In a study of 248 patients with proven GCA, however, 23 had a widespread arteritis, and three of these 23 patients presented solely with symptoms due to vasculitis of the lower extremities [5]. Here we present the capacity of high-resolution MRI to depict the unusual vascular involvement in a 65-yr-old man with proven GCA.
