Cardiac MRI. Cardiac MRI was performed with axial sequence white blood, black blood, cine short axis, 4-chamber, 2-chamber, short axis, T2 Short Tau Inversion Recovery (STIR), Look-locker, LGE with Multihance contrast 0.5 mmol/mL, 12 mL. Balance Turbo Field Echo (BTFE) horizontal long axis 4-chambers view aA) showed the mass near the RA was intrapericardial. BTFE ventricular long axis focused-RV view (b) showed compression of superior vena cava (asterisk, *) and intrapericardial mass at RV free wall, demonstrated with BTFE—breath-hold (short-axis view) (c). Low T1 mapping signal on look-locker sequence (d), and heterogeneously high T2 signal ratio (e) evaluated with T2 STIR, with no evidence of gadolinium enhancement (f) with LGE Phase Sensitive Inversion Recovery (PSIR) confirmed the diagnosis of subacute–chronic pericardial hematoma
