History of rectal cancer status post chemoradiation therapy. Evaluate extent of disease. PELVIS:UTERUS, ADNEXA: The uterus is normal in size. It appears to be partially septated with a muscular septum. The endometrium is normal in thickness.Redemonstrated 6.1 x 4.6 cm left adnexal cyst with a thin septation but no abnormal enhancing components. The right adnexa is unremarkable.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: The previously seen low rectal circumferential wall thickening is significantly decreased in size measuring approximately 7 mm in maximal thickness compared to 11 mm previously at the 1:00 position. The longitudinal of the lesion is difficult to accurately measure. There is no definite post-contrast enhancement or significant restricted diffusion. The inferior margin of the tumor is approximately 2 to 3 cm the anal verge. There are very small mesorectal lymph nodes, the largest measuring 3 mm in short axis (series 1001/28) at the 5:00 position. One very small lymph node appears to abut the mesorectal fascia (series 1001/29) at the 4:00 position, decreased in size.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
Interval decrease in circumferential wall thickening of the distal rectum. There are small mesorectal lymph nodes as described above one of which appears to abut the mesorectal fascia.6.1 cm left adnexal cystic lesion without suspicious mural nodularity or enhancement.
