Figure 29: MPM of the right lung in a 58-year-old man. Panel A Axial T1-weighted (869/12) MR image shows multiple pleural masses of moderate signal intensity encasing the right lung (arrowheads) and a pleural effusion of lower signal intensity (open arrow). A right hydropneumothorax (solid arrow) can be seen anteriorly. Panel B Axial T2-weighted (2,571/90) MR image at a similar level allows differentiation between the tumor (curved arrow), which has intermediate signal intensity, and the pericardial effusion (straight arrow) and pleural fluid, which have high signal intensity. Panel C Coronal T1-weighted (895/20) MR image shows the intermediate signal intensity of the tumor mass in the inferior portion of the contracted right hemithorax. The tumor is invading the pericardium (arrow) and obscuring the high signal intensity of the pericardial fat.
