Female 42 years old Reason: relationship of rectal cancer to posterior vagina History: new diagnosis of rectal cancer Overall image quality: GoodPELVIS:UTERUS, ADNEXA: Invasion of the posterior cervix as below. BLADDER: No significant abnormality noted. LYMPH NODES: Lymph nodes in the perirectal space, within the mesorectal fascia: NoneLymph nodes outside the mesorectal fascia: NoneBOWEL, MESENTERY: Rectal Tumor:Size: 1.9 x 3.4 x 12.5 cm (image 37/series 3 and image 21/series 4)Tumor appearance on T2-weighted images: Circumferential tumor with large soft tissue component along the left aspect of the rectum.Tumor location: Extending from the anal verge 12.5 cm proximally, involving the rectum and proximal sigmoid colon(For lower rectal tumors):Distance of the lower edge of the tumor to the anal verge (lower edge of the anal canal): 1.4 cmDistance of the lower edge of the tumor to the pelvic floor (relationship of the tumor to the anal sphincter complex): Extends from the anal sphincter proximally.Circumference of the rectum involved: Complete circumferential distally but proximally occupies 180 degrees along the left aspectRelationship and proximity of the tumor to adjacent structures (uterus, cervix, vagina): There is invasion of the adjacent mesorectal fat and fascia as well as invasion into the posterior wall of the upper vagina and cervix (4/22 and 3/38).MRI T-stage: T4 - Tumor invades adjacent organs, as described aboveTumor Distance to Mesorectal Fascia: 0 cm (image 3/series 40).BONES, SOFT TISSUES: No significant abnormality noted.OTHER: Small amount of free fluid, likely physiologic.
