  "abstract": "A male in his 20s with good past health presented to the clinic with a 1-month history of fever, polyarthritis and myalgia in the lower limbs. Physical examination revealed diastolic blood pressure of 110 mm Hg and diminished pulsation of dorsalis pedis arteries. Laboratory data showed elevated inflammatory markers, but tests for autoimmune antibodies, cardiac enzymes and infectious diseases were all negative. Electromyogram of the lower limbs showed peroneal and tibial neuropathies. Transthoracic echocardiography revealed elevated pulmonary artery pressure (40 mm Hg) with normal chamber size and function. The patient reported a 6 kg unintentional weight loss and the development of interdigital ulcerations on the feet over the following month. Whole-body positron emission tomography (PET) scan showed two focal strong fluorodeoxyglucose (FDG) avidities of coronary arteries (standardised uptake value maximum (SUVmax)=7.89) and diffuse FDG uptake in the vessels of all limbs (SUVmax=2.92) ( figure 1). Reconstruction coronary CT angiography disclosed diffuse lumen stenosis and aneurysm change of left anterior descending artery, suggesting chronic inflammation (figure 2). Conventional angiography illustrated diffuse stenosis and aneurysm change of tibial arteries with collateral flow (figure 3).",
