Figure 14.

Histologically proven cardiac primary well-differentiated liposarcoma incidentally detected on a CT scan in a 73-year-old patient presenting with chest pain and dyspnea. The noncontrast CT axial image shows a hypoattenuating solid mass (asterisk) with prevalent negative densitometric values, inhomogeneous content, and irregular margins, extending from the right atrium into the right ventricle through the tricuspid valve, as for an infiltrative behaviour. A mild amount of pericardial fluid is also noted.
