- fine linear calcs, in one area
- NOT plasma cell mastitis unless more diffuse
- incidence of breast ca in women
- 1/8 over lifetime
- breast densities
-
Fatty
scattered fibroglandular densities (thats what it means)
Heterogeneously dense (50-75 % glandular)
Dense - findings that must be looked for in each case
-
Density -- can obscure mass
Masses
Calcifications
Architectural distortion - What is the percent cutoff for Birads 3?
- 98% chance it is benign
- Lactating patient presents with breast lump
- When there is a palpable area of clinical concern (PACC), you will perform an ultrasound and evaluate the lump. If no mass is found, you will perform a single MLO view to look for microcalcifications.
- Lactating patient for screening mammo
- NO. No screening during lactation because the breasts are too damn dense.
- Bilateral diffuse breast pain
- No US is performed. Mammo is done to evaluate density, skin thickening. Only would do US if there was a PACC.
- Missed on MLO view
- medial breast
- missed on CC view
- far lateral breast. That's why we sometimes need exaggerated CC views.
- Irregular lesion, posterior medial breast on CC view
- sternalis muscle. It can have irregular surface, and is commonly flame shaped. It will not be visible on the MLO view or ML view because of its far posterior location.
- Posterior mass overlying the pectoralis muscle
- spot compression view.
- Numerous calcifications in tail of Spence on ML of view
- make sure this does not represent deodorant. Question patient, have patient clean area with towel, and repeat study.
