Provided history of recurrent rectal cancer. Concern for vaginal extension. PELVIS:UTERUS, ADNEXA: 3.7 x 3.3 cm submucosal/intramural left uterine body well-defined mass with punctate cystic foci and postcontrast enhancement likely represents a fibroid and less likely focal adenomyoma. The visualized endometrium is unremarkable otherwise.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Approximately 3 to 4 cm above the anal verge there is a 1.8 x 1.7 cm round soft tissue mass abutting the right anterolateral aspect of the rectum without a distinguishable fat plane and irregularity of the rectal wall at this level. Additionally the mass abuts the posterior right vaginal cuff wall, without a distinguishable fat plane. The mass demonstrates postcontrast enhancement most significantly around the periphery. The surrounding mucosa demonstrates normal enhancement.The lesion abuts the adjacent right levator ani musculature.There is a 3 mm perirectal lymph node (series 401/41) at the 7 o'clock position. BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1.8 cm enhancing soft tissue mass in between the right anterolateral aspect of the rectum and posterior right vaginal cuff wall. Its imaging appearance is unusual for the given history of rectal cancer, and sampling should be considered as this may represent a vaginal neoplasm extending into and invading the rectum.
