Amorphous calcification within breast

Dr Henry Knipe and Dr Yuranga Weerakkody et al.

Amorphous or indistinct calcifications are a morphological descriptive term for breast calcification and are defined as having small, hazy, faint calcifications with no clearly defined shape or form. 

Radiographic features

  • 80-200 micrometer in diameter
  • small, hazy calcification
  • often magnification views required (utilizing a microfocal spot and an air gap)
  • when clustered/segmental in distribution: is considered suspicious
  • interval change is considered suspicious
 BIRADS categories
  • BI-RADS II: when diffuse and bilateral
  • BI-RADS III: when multiple bilateral clustered
  • BI-RADS IV: when unilateral clustered or new on follow up or in a patient with a cancer in the contralateral breast

Associations

Many benign and malignant conditions may be seen in association with these calcifications 1.

Due to this some amorphous calcifications can be classified as suspicious calcifications.

Depending on their distribution they can fall into a range of BIRADS categories.
