Introduction:
Takayasu arteritis (TA) is an inflammatory arteritis affecting large vessels, predominantly the aorta, its main branches, and the pulmonary arteries. Up to now, arteriography was considered as the "gold standard". But others exams are emerging in the management of TA: vascular ultrasound, angio-scanner, magnetic resonance imaging and 18FDG positron emission tomography (18FDG PET). Such investigations allow a study of the lumen but also of the arterial walls. However, at the time, no biological or radiological test is able to determine the activity of TA. 18FDG PET could be effective to estimate the disease activity.
Exegesis:
We report the case of a young woman for who 18FDG PET permit to assert a relapse of TA.
Conclusion:
18FDG PET could be effective to estimate the disease activity.
