Sample item

Which ultrasound feature more often favors a benign breast cyst?

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

The answer and the reasoning

B. Anechoic lesion with posterior acoustic enhancement and thin smooth wall

A simple cyst is typically anechoic, thin walled, sharply circumscribed, and demonstrates posterior enhancement. Solid irregular shadowing lesions warrant a different level of concern.

Option by option

  • A. Pleomorphic microcalcifications only

    Microcalcifications are evaluated primarily on mammography.

  • B. Anechoic lesion with posterior acoustic enhancement and thin smooth wall (correct)

    Correct. This is the classic simple-cyst ultrasound appearance.

  • C. Skin thickening with nipple retraction

    Skin and nipple changes can be malignant features.

  • D. Irregular spiculated hypoechoic mass with shadowing

    Irregular spiculation and shadowing raise concern for malignancy.
