10. What to say

11. “The breasts are heterogenously dense”
“There is a focal asymmetry in the
superior and central right breast”
“This is a BIRADS 0, additional evaluation
is required”

12. ------------------------------------------------------------------------------------------------
“I would do a lateral view, spot
compression and an ultrasound”
“The focal asymmetry persists on the lateral and spot
views. Ultrasound demonstrates an irregular
hypoechoic mass with posterior acoustic shadowing”
“This is a suspicious mass. BIRADS 4, biopsy is
recommended.”

13. Final BIRADS at Boards
Avoid BIRADS 3
All cases will be BIRADS 2 Benign
or
BIRADS 4 Suspicious

15. Case 1

19. Case 1: Solid mass
1. Specific diagnosis is not important
2. How to workup the finding is the key
3. Be consistent –
Suspicious descriptors  BIRADS 4
Benign descriptors  BIRADS 2

20. Mass Workup
Lateral
Spot Mag
Ultrasound

21. Mass descriptors - Mammo
Shape (round, oval, lobular, irregular)
Margins (well-circumscribed, microlobulated,
partially obscured, indistinct, spiculated)
Density (high density, isodense, low density,
fat-containing)

22. Mass descriptors - US
Shape (oval, round, irregular)
Echogenicity (anechoic, hyperechoic, complex/mixed,
hypoechoic, isoechoic)
Margins (well-circumscribed, indistinct, angular,
microlobulated, spiculated)
Orientation (wider than tall, taller than wide)
Posterior features (shadowing, increased thru transmission, none)

23. For the boards:
We biopsy all new solid
masses

24. Case 2

27. You can use the mouse as
a magnifying glass
during the exam

29. Case 2: Suspicious calcifications

30. Calcifications

31. Case 3

35. Case 3: Suspicious focal
asymmetry

36. Focal asymmetry /
Architectural distortion
Lateral
Spot Compression
+/- Ultrasound
Same workup for architectural
distortion as for focal asymmetry

37. Case 4

39. Rolled views

40. Case 4: Suspicious asymmetry

41. Asymmetry
Only on CC
Rolled CC’s
Spot compression
Only on MLO
Lateral

42. Case 5

47. Case 5: Suspicious
palpable mass
Always look
for a BB on
the skin =
palpable

48. Palpable Workup
Put BB on skin
