Radiology · Gynaecological imaging: O-RADS ultrasound

Sample item

An ultrasound of the adnexa shows a unilocular cyst of 4 cm with smooth thin walls and anechoic contents in a premenopausal woman. How is it classified in a risk stratification system such as O-RADS?

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

The answer and the reasoning

D. Almost certainly benign, with a very low risk of malignancy

Simple cysts in premenopausal women have a very low malignancy risk and often require no follow-up if below 5 cm. O-RADS and similar systems assign higher risk to solid components, papillary projections and flow.

Option by option

  • A. Cannot be assessed

    A simple cyst can be assessed reliably by ultrasound.

  • B. High risk of malignancy

    High risk requires solid or irregular features.

  • C. Definitely malignant

    A simple cyst is not malignant.

  • D. Almost certainly benign, with a very low risk of malignancy (correct)

    Correct. A simple unilocular cyst is classified as almost certainly benign.
