Abstract
CASE REPORT: We report the case of a patient with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis with involvement of the temporal artery, presenting with clinical manifestations of giant cell arteritis and temporal arteritis, such as temporal headache, jaw claudication, weight loss, night sweats and increased inflammatory parameters. The ultrasound scan showed a typical halo sign of the temporal artery. DIAGNOSTICS: In the case of further atypical organ symptoms, e.g. hematuria and proteinuria, detailed differential diagnostic investigations are essential to clarify the situation. Histological findings from the affected organs play a decisive role. CONCLUSION: An involvement of the temporal artery due to ANCA-associated vasculitis is extremely rare and may mimic giant cell arteritis. The exact diagnosis of ANCA-associated vasculitis is, however, important because this leads to a different approach concerning therapy and prognosis.
