Magnification Views:
Dose Contrast Exposure |
Mag views have higher dose and exposure time.
Contrast is same. |
|
|

Who? |
Tubular carcinoma is most common in women aged 40–60 years
|
|
|
Tubular Carcinoma:
Prognosis? |
The prognosis for pure tubular carcinoma is excellent
|
|
|
Tubular Carcinoma:
Mammogram findings? |
Like a radial scar...
-translucent, oval or circular areas at the center of the radiating structure -long, thin spicules and clumped spicules |
|
|

|
|
Medullary Breast Cancer:
Mammographic Findings |
Round or Oval mass
Lobulations/Serrations at Margin Noncalcified |
|
|
Focal asymetric density
|
It is visible as asymmetry of tissue density with similar shape on two views, but completely lacking borders and the conspicuity of a true mass
|
|
|
Architectural distortion
|
Distorted with no definite mass visible.
Includes: Spiculations radiating from a point Focal retraction or distortion of the edge of the parenchyma |
|
|
Eggshell / Rim Calcifications
|
thin calcified capsules of spherical BENIGN lesions in the breast.
-usually cysts, but fibroadenomas may sometimes calcify in a fine, rim like fashion. -delicate, lace-like -may compromise ultrasound |
|
|
MILK OF CALCIUM
|
-precipitated, amorphous calcium particles, floating within small cysts
-tea cup appearance |
|
|
DYSTROPHIC
|
irregular, dense, sometimes inhomogeneous, appear in post-irradiated breast or following trauma, including surgery.
|
|
|
PUNCTATE CA++
|
-small, less than 5 mm.
-regular, dense, pinpoint, round or oval deposits. -represent involuting breast structures -BIRADS II |
|
|
AMORPHOUS or INDISTINCT CA++
|
-Round, flake-shaped, small and hazy, calcifications that do not change position
-may be innumerable small particles glued together on mag views -Intracystic calcifications v adenosis v cancer BIRADS III or IV |
|
|
HETEROGENEOUS or PLEOMORPHIC CA++
|
-granular, comma-shaped, pointed, fine linear interrupted or branching types, which can be irregular in shape and of different size
-BIRADS IV or V |
|
|
CASTING CA++
|
-distinctive fine, linear, branching pattern
-formed by necrotic tissue in duct -BIRADS V |
|
|
