Results
The most characteristical findings were an extra-cardiac mass and pericardial effusion.
TTE detected the mass in 5 pts (50%; mean major mass diameter 31 mm; range 25– 37 mm),
whereas CMR detected the mass in all pts (100%; mean major mass diameter 27 mm; range 15–40 mm), and better defined peri- ed extra- cardiac involvement,
showing extension to the right atrioventricular sulcus,
right atrial free wall,
right coronary artery and contiguous vessels.
Detected mass had no specific ultrasound features,
whereas at CMR had distinctive features: dishomogeneous intensity in STIR,
rapid enhancement during perfusion and peculiar intensity in late enhancement.
Circumpherential pericardial effusion was detected in 6 pts at TTE (60%) whereas in 8 pts at CMR (80%).
Pericardial thickening was present in 2 pts at TTE (20%),
in 8 pts at CMR (80%).

CMR and TTE findings
Furthermore CMR showed RV-EDV reduced in 7 pts (70%; mean value 109.8 mL),
RV diastolic function impaired in all patients ,
LV-EDV reduced in 5 pts (50%; mean value 117.9 mL),
LV diastolic disfunction impaired in 9 pts (90%).
