Most of the scientific evidence for clinical treatment has been limited to case reports. The aim of this retrospective study is to review the antenatal natural history, maternal and fetal complications, and the therapeutic modalities used in pregnancies complicated with placental chorioangioma in King Faisal Specialist Hospital and Research Centre (KFSHRC).

Data collected by the investigators, entered on Excel sheets in encrypted format or directly in a software system. Results: Over a 10-year period from January 2010 till December 2019, 10 cases were idenitified to have Choriangiomas. Ultrasound remains the gold standard modality for diagnosis and follow-up of the pregnancy. 6 of the 10 cases were chorioangioma was detected by ultrasound. This allowed proper fetal surveillance and antenatal follow-up. In our study one case under went radiofrequency ablation.
