Figure 3 Case 3. (a) Sagittal T2-weighted images show a rectosigmoid mass involving upper rectum with about 15 cm from anal verge. (b) Axial T2-weighted images show endophytic mass of intermediate signal intensity infiltrating rectal wall between 11 o’clock and 12 o’clock position in circumferential location and invading mesorectal fascia to reach to anterior peritoneum. (d) Coronal T2-weighted images show an upper rectal mass and perirectal fat with no evidence of EXMVI or perirectal lymph node. (e) Diffusion-weighted image shows rectal mass of restrictive diffusion that invades mesorectal fascia.
