MASS

Occupies space

Should be seen in two different projections

background echotexture
Background Echotexture
  • Breast tissue Variable
  • Homogenous-Fat
  • Homogenous-Fibroglandular
  • Heterogenous

MASS
  • Occupies space
  • Should be seen in two different projections
mass margin
Mass -Margin
  • Circumscribed
  • Not Circumscribed:
  • Ill defined
  • Angular
  • Microlobulated
  • Spiculated
mass echo pattern
Mass –Echo Pattern
  • Anechoic
  • Hyperechoic( relative to FAT)
  • Complex( heterogenous)
  • Hypoechoic
  • Isoechoic
mass surrounding tissue
Mass Surrounding Tissue
  • Architectural distortion
  • Skin Thickening (Normal-2 mm)
  • Skin Retraction
  • Edema (Inflammatory Ca., radiation, mastitis,CHF )
