MRI of the rectum with and without contrast in a coronal view displays a heterogeneously enhancing mixed solid and cystic lesion in the extraperitoneal pelvic region, marked by red arrow. This lesion, predominantly centered in the retro-rectal space, exerts pressure on the rectum, pushing it anterolaterally as indicated by yellow arrows, causing mass effect and probable luminal narrowing of the mid rectum. Additionally, as shown by blue arrow, the lesion is pushing the rectovaginal fascia anteriorly with possible extension into the lower posterior wall of the vagina.
