Male 74 years old Reason: rectal cancer History: rectal cancer Overall image quality: ExcellentPELVIS:PROSTATE/SEMINAL VESICLES: No significant abnormality noted.BLADDER: No significant abnormality noted. LYMPH NODES: Lymph nodes in the perirectal space, within the mesorectal fascia: There is a small lymph node within the left posterior lateral mesorectal fat measuring 0.8 x 0.7 cm (5/26), 4 mm from the mesorectal fascia. From this node, there is extension of soft tissue nodularity along vessels in the mesorectal fat, likely representing lymphovascular invasion (5/20). This soft tissue extends 5 mm from the mesorectal fascia.Lymph nodes outside the mesorectal fascia: NoneBOWEL, MESENTERY: Rectal Tumor:Size: Circumferential thickening distally measuring 1.3 cm in thickness (4/19). There is a more nodular component along the right anterolateral aspect measuring 2.4 x 1.7 cm (5/29).Tumor appearance on T2-weighted images: Hyperintense with areas of susceptibility artifact distally, likely reflecting hemosiderin deposition from prior biopsy.Tumor location: Middle-third(For lower rectal tumors):Distance of the lower edge of the tumor to the anal verge (lower edge of the anal canal): 8 cmDistance of the lower edge of the tumor to the pelvic floor (relationship of the tumor to the anal sphincter complex): 4 cmCircumference of the rectum involved: Entire circumference.Relationship and proximity of the tumor to adjacent structures (prostate, seminal vesicles): The tumor invades through the muscularis propria at the mid aspect of the tumor, approximately 7 mm into the mesorectal fat, both along the left lateral aspect and posterior aspect (5/29). There is no involvement of the mesorectal fascia. There is no involvement of the prostate, seminal vesicles or bladder. MRI T-stage: T3c - Tumor invades >1cm into perirectal fat or extramuralTumor Distance to Mesorectal Fascia: 1.1 cm (image 29/series 5).BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.Circumferential rectal cancer measuring 5 cm in length, invading into the mesorectal fat, consistent with a stage 3c tumor by MR.2.Enlarged mesorectal lymph node 4 mm from the mesorectal fascia with soft tissue extending along small vessels in the mesorectal fat, likely representing lymphovascular invasion.
