MSFinals-3316
A 26-year-old woman presents to the Emergency Department with minimal vaginal bleeding. She reports her last menstrual period as having been 4 weeks ago. She denies pain but reports severe nausea and vomiting. She has no significant past medical history and her last check-up 6 months ago did not reveal any abnormalities. On examination, her blood pressure is 160/110 mmHg and her uterus measures 12 weeks’ size. A serum beta human chorionic gonadotropin (β-HCG) level is drawn and found to be in excess of 300 000 iu. An ultrasound does not identify any foetal parts. What is this patient at risk of developing?
