Rare Case of Parametrial Molar Pregnancy With Typical Imaging of Ultrasound and Magnetic Resonance Imaging: A Case Report.

This case presents the diagnosis and management of a rare ectopic molar pregnancy. A 31-year-old woman developed intermittent vaginal bleeding after presumed induced abortion 6 months ago. Elevated serum level of 𝛽-HCG and multimodal imaging confirmed the diagnosis of parametrial molar pregnancy. The patient underwent laparoscopic surgery combined with chemotherapy and immunotherapy. She has maintained complete remission for 1 year with normal range of serum 𝛽-HCG. This case underscores the characteristic imaging features of ultrasound and magnetic resonance imaging of ectopic molar pregnancy. Familiarity with these specific signs may facilitate accurate preoperative diagnosis of this rare disease.
