Figure 1
The contrast-enhanced CT image of the patient shows hypodense mass lesion with a size of 5.5 × 6 × 5.5 cm in the interventricular septum (arrow). The lesion has thick and slightly irregular capsule with internal septations.
Figure 2
The four chamber view images of the patient on steady-state free precision MRI during the diastole (a) and the systole (b). The lesion has hyperintense signal with internal septations. Also, note that the mid-ventricular and apical part of the left ventricular cavity is substantially obliterated by the mass during the systole (short arrow).
