Coronary artery aneurysm masquerading as a paracardiac mass on transesophageal echocardiography

Eighteen Years of Follow-up after Resection of a Giant Coronary Artery Aneurysm and Reconstruction with a Vein Graft

“…Previous studies have reported that coronary artery aneurysms could be misdiagnosed as paracardiac or intracardiac masses [ 3 , 4 ]. In this case, only CT was performed preoperatively, and the mass-like lesion in the right heart was initially misdiagnosed as an intramural hematoma of the ascending aorta.…”

Coronary Artery Pseudoaneurysm due to Medial Mucoid Degeneration Mimicking an Intra-atrial Mass

“…Coronary artery aneurysms can occasionally be difficult to diagnose despite the availability of multiple cardiac imaging modalities, including CAG, MRI, TTE, and transesophageal echocardiography (TEE), and they may clinically present as cardiac (intracardiac and myocardial) or paracardiac masses (5,6,(13)(14)(15)(16)(17)(18)(19)(20)(21)(22). Thus far, ten cases of coronary artery aneurysms mimicking cardiac masses have been reported (Table) (5,6,(13)(14)(15)(16)(17)(18).…”

MRI of congenital coronary artery aneurysm.

“…The diagnosis of coronary artery aneurysm is usually made angiographically or by transoesophageal echocardiography [8]. The latter is particularly useful in identifying saphenous vein graft aneurysms in which coronary angiography was of limited value owing to proximal stenosis and insuf®cient¯ow [9].…”
