Figure 1: Images of patient J.S. and Takayasu’s arteritis (a) Patient J.S. CT angiogram of abdomen and pelvis from 12/31/2009. Sagittal reconstruction showing severe calcifications along the abdominal aorta. (b) Patient J.S. CT angiogram of abdomen and pelvis from 12/31/2009. Coronal reconstructions showing severe abdominal aortic vessel calcification. (c) Patient J.S. MRA of abdomen and pelvis from 09/08/2009. 3D angiogram showing severe abdominal aortic calcifications along length of abdominal aorta, a small right kidney, moderate grade SMA stenosis, low signal in the right renal artery concerning for right renal artery stenosis or right renal artery occlusion, and narrowing of the bilateral iliac and femoral arteries (d) Patient J.S. Doppler flow of left external carotid artery from 01/20/2010. It shows a 50-69% stenosis, as well as notable intimal thickening all along the bilateral carotid arteries, including the left common carotid artery. (e) Renal ultrasound with Doppler from 03/16/2009. It shows an abnormally small right kidney measuring 6.1 cm, right renal artery with high resistance waveform and no diastolic flow suspicious for renal-artery occlusion versus stenosis.
