Secondary rectal linitis plastica caused by prostatic adenocarcinoma - magnetic resonance imaging findings and dissemination pathways: A case report

Figure 4 Magnetic resonance imaging images of case 1 demonstrating concentric "target-like" involvement of the rectal parietal wall due to secondary linitis plastica. A: The axial images obtained from T2 turbo spin echo sequence; B: Diffusion-weighted imaging (DWI); C: T1 gradient recalled echo volumetric interpolated breath-hold examination with contrast-enhanced subtraction technique revealed a stratified parietal thickening of the rectal wall. This thickening displayed concentric areas of intermediate signal intensity on T2-weighted images, restricted diffusion on DWI, and enhancement on contrast-enhanced images, affecting both the submucosal (arrow) and muscular (arrowhead) layers.
