Case number:091
Clinical presentation:Perimenopausal woman presented for mammography screening. She has no risk factor on examination and no significant abnormality is detected.


Breast composition:ACR category d (the breasts are extremely dense, which lowers the sensitivity of mammography)
Mammography features:

 ‣ Location of the lesion:Bilateral breasts, all quadrants, all zones
 ‣ Mass:
   • Number:0
   • Size:None
   • Shape:None
   • Margins:None
   • Density:None
 ‣ Calcifications:
   • Typically benign:Round; a few are round with lucent centres and a few are rod-like
   • Suspicious:None
   • Distribution:Diffuse
 ‣ Architectural distortion:None
 ‣ Asymmetry:None
 ‣ Intramammary node:None
 ‣ Skin lesion:None
 ‣ Solitary dilated duct:None
 ‣ Associated features:None


BI-RADS Category: 2 (benign)

Case summary:

Perimenopausal woman with average risk of developing breast cancer presented for mammography screening. Diagnosed as typically benign, round, rim, and rod-like calcifications seen in diffuse distribution in both breasts, BI-RADS 2 on imaging.

Learning points:

  • Breast parenchymal calcifications seen in both breasts and scattered in all quadrants in diffuse distribution indicate benign process. These calcifications have remained stable on follow-up mammograms and can be ignored.
