Takayasu’s arteritis (TA) is an uncommon chronic vasculitis of unknown origin that affects large and medium sized arteries, especially the aorta, its branches and pulmonary arteries.1,2 TA may present as fever of unknown origin (FUO),3 and inflammatory cells have been shown to take up [18F]fluorodeoxyglucose ([18F]FDG) avidly.4–6

CASE REPORTS

Patient 1

A 27 year old woman was admitted for FUO, headache, and interscapular pain, radiating to the neck and shoulders in the past 2 months. Physical and vascular examinations were normal. Laboratory tests showed anaemia (haemoglobin 84 g/l) and a raised erythrocyte sedimentation rate (ESR 79 mm/1st h). Blood cultures, a Venereal Disease Research Laboratory (VDRL) test, and autoimmune serological findings were negative. Vascular magnetic resonance (VMR) was normal. [18F]FDG positron emission tomography ([18F]FDG-PET) showed hypermetabolism in the brachiocephalic trunk, left carotid artery, and thoracic aorta (fig 1A).
