Spiegelberg described four criteria for diagnosing primary ovarian pregnancy. Which of the following is the fourth criterion?
- A The ipsilateral fallopian tube must be intact and clearly separate from the gestational sac ✓
- B The gestational sac must occupy the exact position of the ovary
- C The sac must be connected to the uterus by the utero-ovarian ligament
- D Ovarian tissue must be attached to the sac by the ovarian ligament
Correct answer: A. The ipsilateral fallopian tube must be intact and clearly separate from the gestational sac
Explanation
Spiegelberg's criteria are: the tube and fimbriae are intact and separate from the sac, the gestational sac occupies the normal position of the ovary, the sac is connected to the uterus by the utero-ovarian ligament, and ovarian tissue is attached to the sac wall by the ovarian ligament. Option A states the intact ipsilateral tube, which is the fourth criterion. Options B, C and D each restate the first, third and second criteria respectively.
