Scrotal inflammation: An unusual extracranial manifestation of temporal arteritis

Temporal arteritis (Horton disease) is a chronic giant-cell vasculitis involving large and medium-sized arteries. Although it may be widespread, symptomatic vessel inflammation usually involves branches of the arteries originating from the aortic arch and patients present with headaches, amaurosis, jaw claudication or polymyalgia rheumatica. We present the case of a patient with predominant extra-cranial symptomatology (iliac and spermatic), associated with other more typical signs (myalgias, weight loss,...) We will discuss diagnostic difficulties of giant-cell arteritis, indications and modalities of temporal artery biopsy, new imaging diagnostic technics, and treatment.
