Stated history of anal fistula with bleeding. PELVIS:UTERUS, ADNEXA: The uterus is normal in morphology and size. The uterus measures 6.8 x 2.9 cm in sagittal plane. The endometrial cavity/fluid is normal in signal intensity and thickness. The inner myometrium/junctional zone is normal in thickness measuring 6 mm. No discrete uterine mass. The parametrial soft tissues and vaginal canal are unremarkable.There are numerous predominantly peripheral ovarian follicles which are mildly prominent.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: There is a very thin fluid tract extending from approximately the 3:00 of the lower anal canal extending inferiorly in the intersphincteric space and terminating along the left gluteal cleft. This is associated with mild restricted diffusion and postcontrast enhancement. No associated fluid collection. There are small adjacent vessels.There is suggestion of mild hyperenhancement of the visualized rectosigmoid colon.BONES, SOFT TISSUES: No significant abnormality noted.OTHER: No significant abnormality noted.
1. Intersphincteric low perianal fistula terminating along the left gluteal cleft without associated fluid collection.2. Suggestion of colitis involving the visualized rectosigmoid colon; correlate for potential inflammatory bowel disease. 3. Numerous predominantly peripheral ovarian follicles which are mildly prominent; correlate for clinical signs and symptoms of polycystic ovarian syndrome.
