Determining mass origin. Multimodal imaging used to localize and define the mass. (A) Electrocardiogram (ECG)-gated cardiac computed tomography (CT) with intravenous contrast in axial plane, (B) ECG-gated cardiac CT with intravenous contrast in sagittal plane, (C) 18-fluorodeoxyglucose positron emission tomography CT scan in the axial plane demonstrating minimal radiotracer uptake into the mass, suggestive of a benign process, and (D) preoperative transesophageal echocardiography demonstrating concern for right ventricular invasion and right ventricular compromise in modified right ventricular inflow-outflow view with colour Doppler demonstrating no flow within the mass. Asterisk = mass; arrow = right ventricle; solid arrowhead = left ventricular outflow tract; open arrowhead = pulmonary artery.

Figure 2
Surgical management of a pericardial vs intracardiac tumour. Intraoperative images demonstrating (A) intracardiac origin of the cystic mass, (B) sharp dissection to enucleate the mass, (C) successfully enucleated 7-cm cystic tumour, and (D) right ventricular defect repaired with a bovine pericardial patch and felt.
