21 year old man with possible pericardial cyst seen on CT, referred for cardiac MRI for further evaluation. Left VentricleThe left ventricle is normal in size with normal systolic function. The overall LV ejection fraction is 61%, the LV end diastolic volume index is 86 ml/m2 (normal range: 74+/-15), the LVEDV is 160 ml (normal range 142+/-34), the LV end systolic volume index is 34 ml/m2 (normal range 25+/-9), the LVESV is 63 ml (normal range 47+/-19). There are no regional wall motion abnormalities present. There is no late gadolinium enhancement to suggest the presence of an underlying fibrosing, infiltrative, or inflammatory process.Left AtriumThe left atrium is normal in size. Right VentricleThe right ventricle is normal in size with normal systolic function. The overall RV ejection fraction is 51%, the RV end diastolic volume index is 92 ml/m2 (normal range 82+/-16), the RVEDV is 171 ml (normal range 142+/-31), the RV end systolic volume index is 45 ml/m2 (normal range 31+/-9), and the RVESV is 84 ml (normal range 54+/-17).Right AtriumThe right atrium is normal in size.Aortic ValveThe aortic valve opens widely and there is no significant aortic regurgitation.Mitral ValveThe mitral valve opens widely and there is no significant mitral regurgitation.Pulmonic ValveThe pulmonic valve opens widely. There is no significant pulmonic regurgitation.Tricuspid ValveThe tricuspid valve opens widely. There is no significant tricuspid regurgitation.AortaThere is a left sided aortic arch with a normal brachiocephalic branching pattern. The aortic root is normal in size.Pulmonary VeinsAll four pulmonary veins drain normally into the left atrium.Pulmonary ArteryThe main pulmonary artery is normal in size.Venous AnatomyThe SVC and IVC drain normally into the right atrium.PericardiumThere is a well delineated, thin walled, homogenous fluid collection attached to the pericardium along the RA free wall in the right cardiophrenic angle. It measures 45mm x 21mm. It is low intensity on T1 imaging, high intensity on T2 imaging and has no late gadolinium enhancement. Based on location and these characteristics, it is consistent with a benign pericardial cyst. There is no pericardial effusion.Extracardiac FindingsThis study is not designed for the specific evaluation of extra-cardiac findings; therefore, the differentiation between artifacts and real extracardiac pathology may be difficult. If clinically indicated, a separate dedicated evaluation should be considered.
1. The left ventricle is normal in size with normal systolic function. The overall LV ejection fraction is 61%.2. The right ventricle is normal in size with normal systolic function. The overall RV ejection fraction is 51%.3. There is a well delineated, thin walled, homogenous fluid collection attached to the pericardium along the RA free wall in the right cardiophrenic angle. It measures 45mm x 21mm. It is low intensity on T1 imaging, high intensity on T2 imaging and has no late gadolinium enhancement. Based on location and these characteristics, it is consistent with a benign pericardial cyst.I personally reviewed the Images and/or procedure with the Resident/Fellow and agree with this report.
