The MRI sequences demonstrate a polypoid pedunculated soft mass within the rectum measuring 7.5 x 6.5 x 5 cm, with the distal edge 8 cm from the anal verge. It shows intermediate signal intensity on T1WI, and T2WI with heterogeneous enhancement following IV contrast, with a shaggy nodular margin and a "cauliflower" appearance. The villi are well visualized with surrounding fluid. The pedicle is attached to the posterior rectal wall, well visualized on axial and coronal sequences. The muscularis propria seems to be involved at the base of the pedicle at 7 o'clock with no evidence of extramural extension. No perirectal lymphadenopathy is seen.
The uterus is diffusely enlarged with multiple leiomyomas of various size, mainly of intramural location.
