Transabdominal and transvaginal pelvic ultrasound images showing a normal appearing anteverted, anti-flexed uterus. Endometrial stripe measures 4mm. Both ovaries are identified. The left ovary has a normal appearance. The right adnexae contains a complex, predominantly cystic mass which has an US appearance most in keeping with a tubo-ovarian abscess. An ectopic pregnancy can not be completely excluded. There is a small amount of free pelvic fluid identified.
