Intracardiac Eustachian Valve Cyst in an Adult Detected with Other Cardiac Anomalies: Usefulness of Multidetector CT in Diagnosis

Abstract

We present an unusual case of an intracardiac Eustachian valve cyst observed concurrently with atresia of the coronary sinus ostium, a persistent left superior vena cava (LSVC) and a bicuspid aortic valve. There have been several echocardiographic reports of Eustachian valve cysts; however, there is no report of multidetector computed tomography (MDCT) findings related to a Eustachian valve cyst. Recently, we observed a Eustachian valve cyst diagnosed on MDCT showing a hypodense cyst at the characteristic location of the Eustachian valve (the junction of the right atrium and inferior vena cava). MDCT also demonstrated additional cardiovascular anomalies including atresia of the coronary sinus ostium and a persistent LSVC and bicuspid aortic valve.

Large right ventricular hydatid cyst in a child: a case report

“…Cardiac thrombus often occurs in patients with underlying heart disease such as atrial fibrillation of reduced ventricular function and presents as a non-echogenic mass. Cardiac blood cyst is usually seen in newborns and mainly affects the atrioventricular valves [ 16 , 17 ]. Cardiac hydatid cyst has a different MRI presentation.…”
