A 69-year-old woman with a history of coronary artery bypass surgery was hospitalized for the purpose of examining an aneurysm of the thoracic aorta. The patient reported back pain 2 weeks prior to admission. Transthoracic echocardiography with a 3.3 MHz probe from parasternal view showed dilated descending aorta (DAo) behind the left atrium. DAo was dilated to 4–5 cm and the left atrium was compressed slightly (Fig. 1a). Thickened inner wall of the aorta vessel was observed (Fig. 1b).

Echo and CT imaging. Parasternal window was obtained from chest and paravertebral approach was obtained from the back. a, b Parasternal long and short axis view. There observed a dilated descending aorta and thickened inner wall of the aorta with suboptimal visibility. c Vertically inverted parasternal window via descending aorta. d Paravertebral approach can visualize thickened inner wall and confirm that there is no blood flow inside. e 3D CT imaging. (Red arrow: parasternal approach, Blue arrow: paravertebral approach). f Dilated descending aorta was approaching the wall of the back. DAo: Descending Aorta, LV: the Left Ventricle, RV: the Right Ventricle
