title: [Choriocarcinoma of the uterus after term pregnancy: imaging by vaginal color Doppler ultrasound].
abstract: A 29 year-old woman presented with continuous metrorrhagia and a positive pregnancy test 3 1/2 months after vaginal birth. Transvaginal sonography showed a 3.5 x 4 x 4 cm mostly echogenic uterine mass with diffuse myometrial invasion in the right fundal region. Colour Doppler sonography revealed extensive low impedance flow in the periphery of the mass suggestive of a trophoblastic tumor. Histological examination of curettage specimens revealed a chorionic carcinoma. The tumor size as measured by magnetic resonance imaging correlated well with that by sonography. Trophoblastic disease after a normal pregnancy is rare. Early diagnosis can be facilitated by transvaginal colour Doppler sonography.
