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

Figure 8 Magnetic resonance imaging findings in case 3. A-C: T2-weighted turbo spin-echo axial imaging (A), diffusion-weighted axial imaging (B), and T1-weighted volumetric interpolated breath-hold examination imaging with contrast-enhanced subtraction (C). The imaging findings revealed a concentric neoplastic involvement of the rectal wall, characterized by areas of intermediate signal intensity on T2-weighted imaging (A), as well as restricted diffusion on diffusion-weighted imaging (correlating with a hypointense region on the apparent diffusion coefficient map, which was not shown; B), and a stratified enhancement pattern on contrast-enhanced imaging (green arrow; C). Notably, the imaging also showed neoplastic involvement of the vesico-rectal plane (white arrow) and the bladder floor wall (green arrowhead).
