Doppler color flow mapping of an invasive mole

We report here Doppler color flow mapping carried out before and after chemotherapy for an invasive mole. This mapping revealed an abnormal color blood flow within the echo-free space in the uterine myometrium, and pulsed Doppler ultrasound showed a prominent arteriovenous shunt flow. Similar features were obtained by pelvic angiography (PAG). After 4 courses of chemotherapy, the area of abnormal colored flow was reduced and findings on the PAG were supportive. The patient is being closely followed, using Doppler color flow mapping.
