Rectal pain/bleeding. Newly diagnosed rectal cancer. Staging exam. Overall image quality: GoodPELVIS:UTERUS, ADNEXA: No significant abnormality noted. BLADDER: No significant abnormality noted. LYMPH NODES: Lymph nodes in the perirectal space, within the mesorectal fascia: Few bilateral nodes measuring up to 8 mm. Lymph nodes outside the mesorectal fascia: A large lymph node mass extends beyond the mesorectal fascia on the left, measuring 3.0 x 2.2 cm (series 601, image 42).BOWEL, MESENTERY: Rectal Tumor:Size: 2.1 x 1.8 x 3.8 cm (image 35/series 601)Tumor appearance on T2-weighted images: Hypointense nodular lesion with central hyperintensity.Tumor location: Left rectum (3:00 position) approximately 3.5 cm from the anus.(For lower rectal tumors):Distance of the lower edge of the tumor to the anal verge (lower edge of the anal canal): 3.5 cm (image 29, series 801).Distance of the lower edge of the tumor to the pelvic floor (relationship of the tumor to the anal sphincter complex): 2.0 cm (image 30, series 801.Circumference of the rectum involved: Approximately 50%.Relationship and proximity of the tumor to adjacent structures (uterus, cervix, vagina): Tumor does not abut the uterus, cervix, or vagina.MRI T-stage: T3c - Tumor invades >1cm into perirectal fat or extramuralTumor Distance to Mesorectal Fascia: Abuts the mesial rectal fascia posterolaterally (image 36/series 601).BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Left rectal mass likely invading through the mesorectal fascia with pelvic adenopathy suspicious for locoregional nodal metastases, as above.
