Free-floating aortic thrombus originating from the right coronary artery

Figure 1: Cardiac computed tomography angiography. (A) Axial–transverse image that shows a low-attenuation material in the right coronary cusp of the sinus of Valsalva. No image suggestive of aortic or coronary dissection was identified. (B) 2D reconstruction in the coronal plane that clearly shows the intracoronary component of a pseudo mass. (C) Thin slab ‘maximum-intensity-projection’ reconstruction in the axial–transverse plane. (D) Thin slab ‘minimum-intensity-projection’ reconstruction showing the extension of the pseudo mass and its relationship to the aortic valve. Similar findings were found on echocardiography that showed no additional anomalies, particularly no intracardiac thrombus and no patent foramen ovale.
