Preoperative diagnosis of primary fallopian tube carcinoma by transvaginal ultrasound, cytological finding and CA-125.

Primary Fallopian tube carcinoma is rarely diagnosed preoperatively. We present the case of a 69-year-old woman with primary tubal carcinoma, which was diagnosed preoperatively on the basis of the cytological finding, characteristic features on transvaginal sonography, transvaginal color flow imaging and elevated CA-125. Transvaginal color Doppler imaging demonstrated the tumor revealed areas of neovascularization with characteristic low impedance (resistance index, 0.34 and pulsatility index, 0.62). Pathohistologic confirmation of the clearcell carcinoma has been done.
