A 27 year-old nulliparous female presents because she's been trying to get pregnant for two years, but has failed. She relates a history of a misdiagnosis of appendicitis that lead to abscess formation when she was 14 years old. Which of the following diagnostic studies would be most helpful at this point in her evaluation?
A TSH level
B hysterosalpingogram
C laparoscopy
D PAP smear
E pelvic ultrasound
Answer: B
While I would disagree that an invasive procedures like HSG should be done first-line, the thing to remember in this question is that the patient has reason to have tubal scarring from adhesions (and there is no better answer listed to choose), so, for a board exam I would choose this answer. The TSH level would not be indicated (she has not had a pg loss), lap could diagnose the tubal scarring but would be done after an abnormal HSG. Pap smear is screening for cervical cancer and not indicated in this case of infertility; and pelvic US would yield nothing diagnostically about the tubes.
