Live Pregnancy With a Coexistent Partial Hydatidiform Mole

A 23 year old Gravida 3 Para 1+1 at 26 weeks and four days of amenorrhea presented at our obstetrics and gynecology clinic for assessment following a coincidental scan that revealed a single live intrauterine fetus in cephalic presentation, longitudinal lie with normal cardiac activity, heart rate of 150 beats per minute, normal gross anatomy and estimated fetal weight of 992 grams. Adjacent to it however was a large monoamniotic echocomplex mass of approximately 398 milliliters with a ‘snow storm’ appearance. Patient was asymptomatic at the time of arrival. She had however had occasional episodes of mild per vaginal bleeding about two weeks prior to visiting the clinic which resolved following treatment from a nearby health center at her home where it was managed as threatening abortion. Previous obstetric history was of a molar pregnancy in her second pregnancy about one year ago where a suction evacuation was notably done and patient improved. The first pregnancy was uneventful throughout the prenatal, perinatal and puerperal time.
