dermal calcifications (“tattoo sign”)
next step for possible skin calcs
tangential views
secretory calcifications: pre or post menopause?
post - don t call them secretory on a premenopausal
if they show you an ML view of calcifications
think of milk of calcium/tea cupping
3 ways to show DCIS on the exam
(1)suspicious calcifications (fine linear branching or fine pleomorphic), (2) non mass like enhancement on MRI, or (3) multiple intraductal masses on galactography.
what happens with skin thickening and trabecular thickening over time?
improves - otherwise it s recurrent disease

what s different about mag views
no grid, smaller focal spot (0.1 mm)
BIRADS 3 = what % cancer
< 2% chance of cancer
BIRADS 5 = what % cancer
> 95% chance of cancer
nipple enhancement on MRI - normal?
yes, normal - don t call it Pagets

upper outer (most tissue)
main blood supply to the breast?
(60%) is via the internal mammary

axilla

which mammo calc pattern has highest suspicion for malignancy?
fine pleomorphic
density of surgical scars related to breast cancer recurrence
Surgical scars should get lighter, if they get denser - think about recurrent cancer.
can you have isolated extracapsular rupture?
nope, always with intra
