Because it is an unusual and serious disease that affects women of reproductive age, as well as because its appropriate treatment results in high cure rates, it is crucial that radiologists be familiar with gestational trophoblastic disease, in order to facilitate its early diagnosis and to ensure appropriate follow-up imaging.

When combined with Doppler flow studies, it is useful not only in the evaluation of GTN but also in the evaluation of the response to treatment and in the detection of GTN recurrence. On T2-weighted images, the tumor presents a heterogeneous, hyperintense mass, with a “bunch of grapes” appearance, that distends the uterus and endometrial cavity Partial hydatidiform mole results from the fertilization of a normal egg by two sperm, resulting in a zygote with a triploid 69,XXY or 69,XXX diandric karyotype When there is cellular involvement, a chest X-ray can show multiple nodules and small, poorly defined opacities, similar to the images produced by inflammatory processes.

Clinical and radiological correlations in patients with gestational trophoblastic disease. Such abnormalities are best viewed in the second trimester. The autopsy revealed metastatic choriocarcinoma of the liver. The uterine vessels can be evaluated by determining their wave gestacionwl, peak systolic velocity, resistance index RIand pulsatility index PI.
The volume of the uterine lesion must be determined because it has an established relationship with the size of the tumor and the risk of chemoresistance Hepatic dona in gestational trophoblastic neoplasia: Surgery and radiotherapy are necessary in some patients with high-risk GTN, especially in those with chemoresistance.

Influence of oral contraceptives in the development Although quite rare, tubal molar pregnancy, as depicted in Figure 5, does occur The treatment is the same as that used in tubal ectopic pregnancy, and the follow-up is similar to that required for intrauterine hydatidiform mole.

These lesions appear late in the course of the disease and are related to poor prognosis. One of the most common treatment regimens is gestacioonal combination of etoposide, methotrexate, and actinomycin-D, alternating weekly with cyclophosphamide plus vincristine Gestational trophoblastic neoplasia, FIGO staging and classification.

Therefore, ultrasound is considered the principal method of diagnosing hydatidiform mole 1,6, After being diagnosed with GTN, patients should first be screened for metastases. The PI of the uterine artery is an indirect measure of functional vasculature of the tumor, being considered a predictor of resistance to chemotherapy, especially to methotrexate, regardless of the FIGO score Trofoblastkca HL, Doyle P.
Although biopsy is contraindicated because of the risk of fatal bleeding 43these lesions can respond to selective chemoembolization.

Routine transvaginal ultrasound at 12 weeks of pregnancy, showing a fetus with normal morphology and a placental area suggestive of complete hydatidiform mole. In the hypovascular form, the tumor has less volume, as well as a higher signal intensity on T1- and T2-weighted images, and a lower rate of uptake of contrast.

The diagnosis should always be confirmed by histopathological examination of tissue obtained through uterine evacuation 2. Imaging of gestational trophoblastic disease. Characteristically, choriocarcinoma is associated with extensive tissue necrosis and hemorrhage In such cases, it is common to identify an embryo, or even a fetus, that is malformed and has gestacinal attachments.
