Transesophageal echocardiography and cardiac MRI correctly identified a suspected right atrial mass seen on transthoracic echocardiography as a prominent crista terminalis in a 26-year-old woman.

Understanding the echocardiographic appearance of a prominent crista terminalis can prevent misdiagnosis of a right atrial mass and avoid unnecessary additional tests.
The crista terminalis is a normal anatomical structure within the right atrium that is not normally visualised in the standard views obtained while performing a transthoracic echocardiogram. In this case report, transthoracic echocardiography suggested the presence of a right atrial mass in a patient with end stage renal disease. However, subsequent transesophageal echocardiography revealed that the right atrial mass was actually a thick muscular bridge in the right atrium consistent with a prominent crista terminalis. An understanding of the anatomy and the echocardiographic appearance of a prominent crista terminalis will minimize the misdiagnosis of this structure avoiding unnecessary expensive additional tests.
Salustri et al. (Tue,) conducted a case report in Prominent crista terminalis mimicking a right atrial mass (n=1). Transesophageal echocardiography (TEE) and Cardiac MRI vs. Transthoracic echocardiography (TTE) was evaluated on Accurate diagnosis of right atrial structure. Transesophageal echocardiography and cardiac MRI correctly identified a suspected right atrial mass seen on transthoracic echocardiography as a prominent crista terminalis in a 26-year-old woman.
