title: Doppler ultrasound in a patient with ovarian Brenner tumor of low malignant potential: comparison with Gray-scale ultrasound, magnetic resonance imaging and tumor marker suggesting malignancy.
abstract: We present a postmenopausal patient with giant lower abdominal tumor. Gray-scale ultrasound and magnetic resonance imaging showed typical abnormal morphology suggesting malignancy. The serum CA 125 level was 69 U/ml, and that of CA 19-9 was 2,097 ng/ml. Transvaginal color and pulsed Doppler sonography of the tumor vasculature demonstrated low peak systolic velocity (6.7 cm/s) with low pulsatility (resistance index: 0.49). Total abdominal hysterectomy and bilateral salpingo-oophorectomy were performed. Histological diagnosis was ovarian Brenner tumor of low malignant potential. Transvaginal Doppler findings seemed to give specific information for the diagnosis in this case.
