Female 73 years old Reason: rectal cancer 1cm from the anal verge History: rectal cancer 1cm from the anal verge PELVIS:UTERUS, ADNEXA: Status post hysterectomy. BLADDER: No significant abnormality noted. LYMPH NODES: Lymph nodes in the perirectal space, within the mesorectal fascia: Note is made of multiple small perirectal lymph nodes, with a reference node, measuring 6 x 4 mm (20; series 4).Lymph nodes outside the mesorectal fascia: Note is made of small external iliac lymph nodes.BOWEL, MESENTERY: Rectal Tumor:Size: 4.9 x 1.3 cm (image 18/series 7)Tumor appearance on T2-weighted images: Heterogeneous, but predominantly increased signal intensity relative to musculature. There is probable invasion to the level of the serosa without convincing evidence of invasion of the mesorectal fat or mesorectal fascia. There is slight upstream dilation of the imaged sigmoid colon.Tumor location: Right anterior and lateral wall of the rectum.(For lower rectal tumors):Distance of the lower edge of the tumor to the anal verge (lower edge of the anal canal): Approximately 2.4 cmCircumference of the rectum involved: 180 degreesBONES, SOFT TISSUES: No bone marrow signal abnormality is identified.OTHER: No significant abnormality noted.
Note is made of eccentric wall thickening with associated increased signal abnormality and enhancement of the rectum, consistent with the stated history of rectal carcinoma, extending to approximately 2.4 cm from the level of the anal verge. There are multiple perirectal lymph nodes in the surrounding area, with reference measurements provided above.
