“…However, there is no large study on the frequency and characteristics of a prominent crista terminalis with transthoracic echocardiography. Furthermore, all seven patients previously reported in case studies of a prominent crista terminalis were women between the ages of 49 and 77 similar to the case reported here 2-6). Therefore, the age and gender of patients with a prominent crista terminalis appear to be similar to the age and gender of patients with a myxoma.…”

A prominent crista terminalis is a normal anatomic variant which consist of thick muscular bridge within the right atrium. However, it could be often misdiagnosed with an abnormal mass on the transthoracic echocardiography. The case report presented here, describe the findings of transthoracic echocardiography that suggested a right atrial mass in patients with pulmonary embolism. However, subsequent transesophageal echocardiography and cardiac computed tomography/magnetic resonance imaging differentiated a true right atrial mass from a prominent crista terminalis.

“…Similar cases of thrombus mimicking cardiac tumours in the atrium have been published,9 – 12 as well as reports of thrombus entrapment in tricuspid chordae mimicking a tumour13 and of a cardiac structure, the crista terminalis, mimicking a mass 14. Finally, there are two descriptions of ventricular thrombus mimicking a tumour, one of which concerns a patient that also has anti-phospholipid syndrome15 and the other a sausage-shaped mass in the right ventricle in a patient with acute pulmonary embolism 16…”

Primary cardiac tumours are a rare occurrence in clinical practice. Mural or pedunculated thrombi are other infrequent findings. These are usually associated with underlying heart disease, present in the left atrium or occupying aneurysms in the ventricular wall, usually the apex. The case of a 33-year-old woman with a pedunculated cardiac mass not having these latter characteristics is reported. She had experienced dyspnoea and lower extremity oedema for 3 years on referral. Echocardiography revealed a mass emerging from the interventricular septum, and a myxoma was suspected. Heart surgery was performed and the findings were a thrombus and large extent of septal and apical mural fibrosis. An endoaneurysmorraphy was performed with exclusion of fibrotic walls from the ventricular cavity.

“…This anatomic structure has gained increased recent attention because the sinoatrial node lies in its superior aspect and its correct localization is important for cardiac electrophysiology studies (28). Occasionally, this prominent muscular band will demonstrate increased FDG activity that may be mistaken for a cardiac mass (29,30) (Fig 9).…”

Patients undergoing 2-[fluorine 18]fluoro-2-deoxy-d-glucose (FDG) whole-body oncologic positron emission tomography (PET)/computed tomography (CT) are studied while fasting. Cardiac FDG uptake in fasted patients has been widely reported as variable. It is important to understand the normal patterns of cardiac FDG activity that can be seen in oncologic FDG PET/CT studies. These include focal and regional patterns of increased FDG myocardial activity. Focal activity can be observed in papillary muscles, the atria, the base, and the distal anteroapical region of the left ventricle. Regional increased cardiac FDG activity may be diffuse or localized in the posterolateral wall or the base of the left ventricle. Abnormal patterns of cardiac FDG activity not related to malignancy include those associated with lipomatous hypertrophy of the interatrial septum, epicardial and pericardial fat, increased atrial activity associated with atrial fibrillation or a prominent crista terminalis, cardiac sarcoidosis, endocarditis, myocarditis, and pericarditis. Knowledge of these patterns of cardiac FDG activity is important to be able to recognize malignant disease involving the paracardiac spaces, myocardium, and pericardium. With a better understanding of the range of normal and abnormal patterns of cardiac FDG activity, important benign and malignant diseases involving the heart and pericardium can be recognized and diagnosed.
