A woman with a positive pregnancy test, left iliac fossa pain and vaginal bleeding has an empty uterus on ultrasound and hCG 2,500 IU/L. What is the likely diagnosis?
Answer and explanation
Correct answer: B. Ectopic pregnancy
- Step 1: An empty uterus with an hCG above the discriminatory zone suggests ectopic pregnancy.
- Step 2: Management is methotrexate or surgery depending on stability.
Answer
Ectopic pregnancy.
Why not the others: 'Complete miscarriage' would show a falling hCG and no pain; 'Molar pregnancy' shows a vesicular pattern and very high hCG; 'Ovarian cyst' does not explain a positive pregnancy test with empty uterus.
