Contrast-enhanced computed tomography and magnetic resonance imaging study at admission. a Contrast-enhanced chest computed tomography shows a large heterogeneous pleural mass involving the right fifth rib and vertebral body. b Contrast-enhanced abdominopelvic computed tomography shows a mass infiltrating the right renal hilum (longest diameter, 44 mm). c Axial T1-weighted magnetic resonance imaging shows a pleural mass with high signal intensity extending to rib, muscle, and vertebral body. d Sagittal T1-weighted magnetic resonance imaging shows a pleural mass with high signal intensity in the right paravertebral area at the level of T3 to T6
