Non-gated axial FIESTA CMR demonstrating hyperintense mass in the interventricular septum (arrow) protruding into the right ventricle. The mass demonstrates mixed intensity regions within and hypointense wall which is of similar intensity and in continuation with the tricuspid valve as well as interventricular septum. The mass has similar intensity to skeletal muscle.Abbreviations: FIESTA, Fast Imaging Employing Steady-state Acquisition.
