Abstract

Purpose : Right ventricular (RV) mass is very uncommon. We retrospectivelyreviewed characteristics of RV mass detected by cardiovascularmagnetic resonance imaging (CMR).Objective : To describe types of RV mass, magnetic resonance (MR) signalintensity, and enhancement of RV mass in CMR.Setting : King Chulalongkorn Memorial Hospital, a large medical school, tertiarycare and cardiac center for treatment of heart diseases in Thailand.Research design : Retrospective review.Methods : CMR studies during Jan 1st, 2007 to July 31st, 2009 were reviewed.All patients who had RV mass were recruited. CMR findings werecorrelated with operative notes, pathology reports and/or clinicaldiagnosis.Result : In total, 243 CMR studies were performed. There were 4 patients(1.65% of total CMR examination) with RV mass: 2 cases were primarycardiac tumor, i.e., malignant fibrosarcoma of right ventricle andbenign RV myxoma; and the other 2 cases were intracardiac thrombus.The tumors showed heterogeneous enhancement whereas noenhancement in the thrombus.Conclusion : CMR is useful to characterize tumor and thrombus by using contrastenhancement.
