Presentation
Breathlessness.
Patient Data
Chest x-ray demonstrates a markedly enlarged cardiac silhouette with splaying of the carina.
The patient went on to have a transthoracic echocardiogram, which confirmed that the heart was indeed markedly enlarged, without an abnormal amount of pericardial fluid. It also demonstrated a focal abnormality, which was further imaged with CT.
Cardiac CT demonstrates the heart to be enlarged. A low density filling defect occupying almost the entire right atrium is also noted. It appears attached to the inter-atrial septum.
Single sequence from a cardiac MRI shows the mass to be of intermediate intensity on T1 weighted imaging.
Case Discussion
This patient went on to have a resection and an atrial myxoma was confirmed histologically.
