Figure 1 Case 1. (a) Sagittal T2-weighted images show a large mass involving upper and mid rectum about 7 cm from anal verge. (b) Axial T2-weighted images show a large circumferential mass of intermediate signal intensity extending beyond the rectal wall with maximum distance from mesorectal fascia of 13 mm (circumferential resection margin=1.3 cm threatened). (c) Coronal T2-weighted images show perirectal fat with no evidence of EXMVI or perirectal lymph node. (d) Diffusion-weighted image shows rectal mass of restrictive diffusion.
