Age:	46
Clinical presentation:	Perimenopausal woman presented for mammography screening. She has no risk factor on examination and no significant abnormality is detected.

Mammography:

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:

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.
