Breast composition:ACR category c (the breasts are heterogeneously dense, which may obscure small masses)
Mammography features:

 ‣ Location of the lesion:Left breast, all quadrants, multiple typically benign round calcifications seen in diffuse distribution. Right breast, lower quadrants, a few round calcifications seen in diffuse distribution
 ‣ Mass:
   • Number:0
   • Size:No mass
   • Shape:None
   • Margins:None
   • Density:None
 ‣ Calcifications:
   • Typically benign:Round
   • Suspicious:None
   • Distribution:Diffuse
 ‣ Architectural distortion:None
 ‣ Asymmetry:None
 ‣ Intramammary node:None
 ‣ Skin lesion:None
 ‣ Solitary dilated duct:None

BI-RADS:

BI-RADS Category: 2 (benign)

Case summary:

Perimenopausal woman with increased risk of developing breast cancer presented for mammography screening. Diagnosed as typically benign calcifications seen in both breasts, BI-RADS 2 on imaging.

Learning points:



  • Round calcifications in diffuse distribution are typically benign calcifications seen in fibrocystic changes and adenosis. Round calcifications that form in the cystically dilated acini of the TDLU are called acinar or lobular calcifications.
