Electrocardiogram and CXR were unremarkable. She underwent cardiac
magnetic resonance imaging(CMR). Her CMR showed a round well defined
mass attached to postero-superior RA wall with a stalk measured 10 x 11
mm without evidence of hemodynamic obstruction or compression. In the
STIR/T2 weighted-sequences, the mass is low signal and in the T1
weighted-sequences with fat suppression images, the mass is low signal.
In the first pass perfusion sequence, the mass has neglible perfusion.
In the early –enhancement imaging, the mass has no enhancement and in
the late-enhancement-sequences, the mass has neglible enhancement. Due
to MRI tissue characterization criteria, cardiac lipoma is the most
likely diagnosis. As a result, we decided to observe the patient with
close follow-up and not perform surgery on the patient. (Figure 2)
