Cardiac hamartoma: Magnetic resonance and computed tomographic imaging

We present a case of a cardiac hamartoma, which is an exceedingly rare, pathologically benign, primary cardiac tumour. We illustrate the imaging appearance of this lesion on CT and MRI, and demonstrate the complementary roles that these two modalities play in the assessment of cardiac masses, specifically in the characterization of fatty content and calcifications. Finally, we offer a discussion of how a cardiac hamartoma may be differentiated from other, more common cardiac masses.
