51-year-old female referred from echocardiography with diagnosis of a right atrial mass with suspected diagnosis of an atrial lipoma.

An MRCP confirms  a lipomatous cardiac mass which is bright on T1 in phase, losing signal on the out of phase and fat sat sequences.

 

The dedicated cardiac MRI confirms the presence of a lipoma of the interatrial septum. There is no evidence of enhancement of the mass.

 

CT of the abdomen and pelvis, revealing the inferior aspect of the heart shows a lipomatous mass.

 

These findings are all therefore consistent with lipoma of the interatrial septum
