Rectal cancer follow-up. PELVIS:UTERUS, ADNEXA: Demonstrated again is a lobular enlarged uterus secondary to numerous well-defined hypodense masses compatible with numerous fibroids. The endometrium/endometrial cavity is distorted.BLADDER: The bladder is normally distended without a focal abnormality. Demonstrated again is abnormal marked symmetric circumferential T2-weighted mildly hyperintense thickening of the urethra extending from the bladder base for approximately 2.6 cm, similar to the prior study. No restricted diffusion or abnormal enhancement is identified.LYMPH NODES: Very small mesorectal lymph nodes are unchanged measuring less than 1 to 2 mm in short axis.BOWEL, MESENTERY: Demonstrated again is asymmetric predominantly very low T2-weighted signal intensity along the anterior lower rectum measuring approximately 2.7 cm in craniocaudal dimension and 1.6 x 0.6 cm in cross-section without restricted diffusion or abnormal postcontrast enhancement, compatible with predominantly post radiation therapeutic changes.BONES, SOFT TISSUES: There are degenerative changes of the spine with grade 2 anterolisthesis of L5 on S1. Fatty marrow changes of the sacrum compatible with post radiation changes.OTHER: No significant abnormality noted.
1.Interval mild decrease in size of the signal abnormality in the anterior distal rectum, demonstrating mostly very low T2-weighted signal intensity compatible with postradiation therapeutic changes.2.Abnormal marked circumferential thickening of the urethra is again seen. Differential considerations favor radiation-related changes, given recent cystoscopy evaluation with no urethral abnormality visualized.3.Enlarged multifibroid uterus.
