a Axial T1 WI, b axial T2 WI, and e coronal T2 WI showing right circumferential nodular pleural thickening mounting to mass formation eliciting heterogeneous predominately low T1 and high T2 signal intensities with evidence of chest wall and diaphragmatic invasion (white arrows). c DWI and d ADC map showing restricted diffusion, with the bright signal on the DWI corresponding to dark signal on the ADC map (ADC mean = 0.45 × 10⁻³ mm²/s). CT-guided biopsy revealed malignant pleural mesothelioma
