case_images: Radioimaging included X-ray sacroiliac joint that revealed grade II bilateral sacroiliitis (grade III right side, grade II left side) (Figure 1(a)). MRI also confirmed bilateral sacroiliitis (Figures 1(b) and 1(c)).
case_images: CT angiogram of the heart and great vessels. Large eccentric structure is noted in the root of the ascending aorta having fistulous communication. A hypodense area is noted within the structure. The structure is compressing the corresponding superior vena cava and left ventricular outlet or aortic root (7.5 mm), suggestive of large aneurysm at the aortic root containing the thrombus.
