What tests are needed for invasive hydatidiform mole?

1. Irregular vaginal bleeding, hemoptysis, cough, headache, vomiting, hemiplegia, etc.

2. Purple-blue metastatic nodules can be seen on the vaginal wall.

3. Enlargement of ovarian lutein cyst and parauterine mass.

4. Blood and urine hcG levels range from low to high, or negative and positive.

5. Multiple cotton-like shadows on the chest can be seen in the online photography.

6. Space-occupying lesions are found in skull section or CT.

7. The trophoblast cells proliferate actively, the tissue undergoes massive necrosis and bleeding, and the villous structure can be seen.

8. Clinical staging: I: the cause is limited to the uterus, II: recent metastasis such as parauterine, adnexa, vagina, etc., III: lung metastasis, and IV: systemic metastasis.

9. Pelvic artery angiography: It is of great significance for the diagnosis of benign and malignant trophoblastic tumors. Malignant hydatidiform mole angiography has dilated uterine arteries, abundant sinusoids, and veins; abundant sinusoids; early venous phase development; long retention time of contrast agent in the lesion. If there are round or semicircular filling defects with sharp edges in the sinusoids, it indicates that malignant hydatidiform mole is more likely. . Pelvic ultrasound examination: B-ultrasound can show that the uterus is enlarged, irregular in shape, with nodules and protruding, and the light spots in the uterine myometrium are dense and uneven.

10. Laboratory diagnosis of hCG: 8 to 12 weeks after the clearance of benign hydatidiform mole, the possibility of malignant hydatidiform mole should be considered if the urine hCG does not return to normal after decreasing or rises again.
