Sample item

A woman with intermenstrual bleeding has a thickened endometrium on transvaginal ultrasound. Which test best distinguishes a focal polyp from diffuse thickening by distending the cavity with saline?

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

The answer and the reasoning

B. Saline infusion sonohysterography

Saline distends the uterine cavity during transvaginal ultrasound so that polyps and submucosal fibroids outline themselves against the fluid, while diffuse hyperplasia appears as a uniformly thick lining. It is also useful to evaluate adhesions.

Option by option

  • A. Bone scan

    A bone scan is irrelevant.

  • B. Saline infusion sonohysterography (correct)

    Correct. Saline infusion outlines focal endometrial lesions.

  • C. Plain pelvic radiograph

    A plain film does not show the endometrium.

  • D. Hysterosalpingography with oil

    HSG does not show the wall detail as well and is mainly for tubal patency.
