Radiology · Ultrasound: ectopic pregnancy

Sample item

A patient with positive pregnancy test, pelvic pain, and vaginal bleeding has no intrauterine pregnancy on transvaginal ultrasound but has an adnexal mass and free pelvic fluid. What is the leading diagnosis?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

C. Ectopic pregnancy

In a symptomatic patient with a positive pregnancy test, an adnexal mass and free fluid without an identified intrauterine pregnancy raise major concern for ectopic pregnancy. Urgent gynecologic assessment is required.

Option by option

  • A. Fibroid uterus

    Fibroids do not account for free fluid and absent intrauterine gestation in this setting.

  • B. Ovarian torsion only

    Torsion can produce an adnexal mass but does not explain the pregnancy-location concern.

  • C. Ectopic pregnancy (correct)

    Correct. This combination is highly concerning for tubal ectopic pregnancy.

  • D. Viable intrauterine pregnancy

    A confirmed viable intrauterine pregnancy would be seen within the uterus.
