- Excessive growth in approximately 1/2 of cases
- Smaller-than-expected growth in approximately 1/3 of cases

Note: All symptoms occur in conjunction with a potential, suspected, or confirmed pregnancy.

Signs and tests:

A pelvic examination may show signs similar to a normal pregnancy, but the uterine size may be abnormal and fetal heart tones are absent. Additionally, some bleeding may be noted.

Tests typically include:

Measurement of serum HCG to confirm pregnancy. Repeated HCG measurements can be used to monitor the rate and consistency of decline if a hydatidiform mole is suspected.
An ultrasound of the pelvis.
A chest X-ray and abdominal CT or MRI will be recommended for some patients.

This disease may also alter the results of the following tests:
