55-year-old male with rectal cancer PELVIS:PROSTATE/SEMINAL VESICLES: Indeterminate subcentimeter T2 hypointense lesion in the medial right peripheral zone - incompletely characterized on this study. BLADDER: No significant abnormality noted.LYMPH NODES: Lymph nodes in the perirectal space, confined by the mesorectal fascia: bilateral lymph nodes with the largest measuring 11 x 13 mm on the right. Lymph nodes outside the mesorectal fascia: none. BOWEL, MESENTERY: There is a mildly enhancing mass in the anterior wall of the rectum that measures 2.8 x 2.0 x 5.7 cm (TR x AP x CC). Tumor appears to involve the muscularis propria although does not definitively extend beyond. Rectal Tumor:Size: 4.4 x 1.8 x 2.9 cm (image 8/series 32)Tumor appearance on T2-weighted images: iso to hyperintense. Tumor location: anterior wall of the lower rectum(For lower rectal tumors):Distance of the lower edge of the tumor to the anal verge (lower edge of the anal canal): 2.3 cmCircumference of the rectum involved: Nearly 360 degree involvement of the rectal wall at the inferior aspect of the tumor. Relationship and proximity of the tumor to adjacent structures (prostate, seminal vesicles): Uninvolved and separated by fat planes. MRI T-stage: T1-T2 - Tumor invades submucosal and/or tumor invades muscularis propriaTumor Distance to Mesorectal Fascia: Anterior tumor without significant mesorectal fat in between tumor rectal wall and pelvic floor muscles (image 4/series 33).BONES, SOFT TISSUES: Probable bone island in the right posterior acetabulum.OTHER: No significant abnormality noted.
1.Lower rectal wall tumor as described above. Enlarged right mesorectal lymph node and additional lymph nodes as above. 2.Indeterminate subcentimeter T2 hypointense lesion in the medial right peripheral zone of the prostate gland. Correlation with PSA is recommended.
