History of vaginal cancer. Perineal pain and bleeding. PELVIS:UTERUS, ADNEXA: Status post hysterectomy.BLADDER: Partially distended urinary bladder.LYMPH NODES: Small left obturator lymph node measuring less than 1 cm in short-axis.BOWEL, MESENTERY: No significant abnormality noted.BONES, SOFT TISSUES: Soft tissue mass centered in the left deep pelvis dorsolateral to the urethra which the mass encases at least 180 degrees (series 501/16) and displaces anterolaterally towards the left (series 501/15). The lesion invades the proximal vagina circumferentially. The lesion extends across the midline between the urethra and vagina towards the right. The lesion has a broad-based abutment with the right levator ani muscle which it displaces leftward (series 501/19) and invades the left levator ani musculature (series 501/19). Additionally there is a fingerlike projection abutting the internal rectal sphincter at several levels (series 501/18-19).The mass extends caudally into the labia, left greater than right. The lesion abuts the cortex of the left inferior pubic ramus. The lesion measures up to 5.1 x 3.5 cm in axial dimension and extends 5.7 cm in the craniocaudal dimension (series 601/27).Heterogeneous mottled bone marrow signal intensity is nonspecific.OTHER: No significant abnormality noted.
Distal vaginal mass with local invasion, including involvement of the external anal sphincter and suspected internal anal sphincter involvement, as described above.Small pelvic lymph node is non-specific.
