(b) Coronal T2-weighted images show rectal mass and perirectal fat with no evidence of EXMVI or perirectal lymph node. (c) Axial T2-weighted images show large circumferential mass of intermediate signal intensity infiltratin the rectal wall and reaching perirectal fat, with maximum distance from mesorectal fascia of 25 mm (circumferential resection margin>2 cm negative). (d) Axial T2-weighted images show a small oval-shaped lymph node of irregular border with short axis diameter of 8 mm.
