A woman at 10 weeks has vaginal bleeding, a uterus larger than dates, a very high hCG and a snowstorm pattern on ultrasound. What is the most likely diagnosis?
Answer and explanation
Correct answer: D. Hydatidiform mole
- Step 1: The picture of a snowstorm ultrasound pattern with a very high hCG fits Hydatidiform mole.
Answer
Hydatidiform mole.
Why not the others: 'Multiple pregnancy': it has a large uterus and two fetuses on ultrasound. 'Threatened miscarriage': it gives bleeding with a viable fetus and a normal hCG. 'Uterine fibroids': they enlarge the uterus without a very high hCG.
