Hepatic metastases on MRI. (a) Axial T1-weighted fat-suppressed precontrast image and (b) postcontrast arterial phase image demonstrating multiple right hepatic lesions with internal enhancement. (c) Axial T2-weighted image shows mildly high signal within the hepatic lesions. (d) Axial diffusion weighted image (B = 800) with high signal within the right hepatic lesions compatible with restricted diffusion.

The patient presented with mild progression of disease on abdominal magnetic resonance imaging (MRI) (Figure 1) after approximately 4 years of stable disease.
(a) Axial bSSFP bright blood image through the right ventricle (RV) shows two masses (yellow arrows) involving the anterior RV wall and basilar interventricular septum. (b) Axial T2 spectral presaturation with inversion recovery dark blood image showing T2 hyperintense signal within the two lesions (yellow arrows). (c) Four-chamber bSSFP bright blood image during late systole shows thickening of the anterior leaflet of the tricuspid valve (open arrow) with an abnormal shortened and retracted configuration near the anterior RV wall mass. (d) Early systole image shows a large low signal tricuspid regurgitant flow jet (blue arrow). Notice the anterior leaflet maintaining an abnormal partially open configuration.

CMR (Figure 2) showed a 2.6 cm lesion in the right ventricular free wall and a 2.4 cm lesion in the left ventricular anteroseptal wall.
