Abstract

Whether an unplanned pregnancy should be terminated during follow-up of a hydatidiform mole is controversial. We report a patient who had an unplanned pregnancy with a hydatidiform mole at 2 months after uterine curettage when the human chorionic gonadotropin level had decreased to a negative value. Hydatidiform mole was confirmed by histopathology. Uterine curettage was performed twice and regular follow-ups were performed after surgery. The patient achieved a full-term pregnancy. The Apgar score of the newborn was 10 at 1, 5, and 10 minutes, and the newborn had no malformations. We conclude that the pregnancy outcome might be good in an unplanned pregnancy when the human chorionic gonadotropin level is negative.

(a) Magnetic resonance imaging shows that the uterus is approximately 12.5 × 6.2 × 7.9 cm in size. A diffusion-weighted imaging scan showed a diffuse hyperintense signal in the uterine myometrium, while the apparent diffusion coefficient showed a low signal. A vascular void signal was observed in the myometrium. (b) Changes in hCG levels in the patient from post-uterine curettage until the end of follow-up. (c) Fluctuation of hCG levels in the patient during pregnancy.
