This case was provisionally diagnosed by ultrasound as a pedunculated subserous myoma originating from the uterine wall as the classic criteria of fibroid lesion were noted. It is very common on ultrasound to confuse a pedunculated myoma and an ovarian fibroma, and the described pedicle proved to be the dilated fallopian tube.

The patient was admitted for myomectomy due to pain with suspected twisted pedicle and ended by left salpingo-oopherectomy.
