Case summary:

Postmenopausal woman with inverted nipple presented for mammography screening. Diagnosed as BI-RADS 1 on imaging.

Learning points:



  • Screening mammography every 2–3 years helps in the early detection of breast cancer and reduces breast cancer mortality. Serial follow-up mammograms reveal the age-related physiological and morphological changes in breast parenchyma.
  • Comparison with earlier mammograms shows involuting breast parenchyma. Breast involution begins many years before menopause and continues into the postmenopausal stage. Glandular atrophy through involution changes the breast density from heterogeneous dense glandular tissue to predominantly fatty breasts as is seen in the follow-up mammogram.
