Preoperative diagnosis of fallopian tube malignancy with transvaginal color doppler ultrasonography and magnetic resonance imaging after negative hysteroscopy for postmenopausal bleeding

Primary fallopian tube carcinoma is a rare malignancy and is not often diagnosed preoperatively. We present a case of a 67-year-old woman who complained of postmenopausal vaginal bleeding. After a negative hysteroscopy, transvaginal ultrasound showed a well vascularized solid-cystic tumor in the adnexal region separate from the ovary. The presence of an adnexal mass was confirmed by MR imaging. Total abdominal hysterectomy with bilateral salpingoophorectomy, omentectomy and appendectomy, as well as pelvic and paraaortic lymphadenectomy was performed. The pathohistological diagnosis was poorly differentiated serous adenocarcinoma of the fallopian tube, FIGO stage IA. The patient was subsequently treated with platinum based adjuvant chemotherapy.
