Preoperative Diagnosis of Fallopian Tube Carcinoma by Transvaginal Sonography, MRI and CA125

Primary fallopian tube carcinoma is the least common of the gynecological malignancies and rarely diagnosed preoperatively. We report the case of a 70-year-old woman with primary tubal carcinoma, which was diagnosed preoperatively on the basis of elevated CA125 and characteristic features found by transvaginal sonography, transvaginal color flow imaging and magnetic resonance imaging. Transvaginal ultrasonography showed a sausage-shaped solid mass alongside the right ovary. Transvaginal color Doppler imaging revealed characteristically low impedance vascular flow within the solid components. A pathohistological study confirmed the diagnosis of fallopian tube carcinoma.
