Radiology · Breast imaging: galactography

Sample item

A woman has spontaneous bloody discharge from a single duct of the left nipple, with a normal mammogram and ultrasound. Which test can show an intraductal lesion?

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

The answer and the reasoning

A. Galactography (ductography) or MRI

Contrast injection into the discharging duct outlines filling defects from intraductal papillomas or cancer, and MRI is an alternative. Single duct bloody discharge usually results from an intraductal papilloma.

Option by option

  • A. Galactography (ductography) or MRI (correct)

    Correct. Ductography shows intraductal lesions.

  • B. Bone scan

    A bone scan assesses the skeleton.

  • C. Chest radiograph

    A chest film does not image the ducts.

  • D. Thyroid ultrasound

    Thyroid ultrasound is unrelated.
