Calcified Unruptured Aneurysm of the Left Sinus of Valsalva

abSt RaCt Aneurysm of sinus of Valsalva is a rare anomaly which can be congenital or acquired. The right coronary sinus is the commonest site of aneurysm formation, with only a few cases reported to arise from the left coronary sinus. Although most patients with unruptured aneurysm of sinus of Valsalva are asymptomatic, fatal complications of unruptured aneurysms of sinus of Valsalva have been reported. These include compression of the coronary artery, ventricular outflow tract obstruction and aneurysm dissecting into the interventricular septum. Thus it is important to recognize the image appearance of aneurysm of sinus of Valsalva to make an accurate diagnosis. In this article, we present an unusual case of unruptured calcified aneurysm arising from the left coronary sinus of Valsalva.
