BRANT: Chapter 21: BI-RADS Flashcards
Pathologic microcalcifications are often associated with necrotic tumor debris. This is most commonly seen with ____
DCIS
Ductal carcinoma in situ (DCIS)
This group of calcifications has the highest likelihood of malignancy of all the calcification morphology descriptors at about 70% and almost always requires biopsy
Fine linear or fine linear branching calcifications
You may see calcifications that look like a “Y” or a “V” that suggest their location within the branches of a milk duct.
Fine pleomorphic calcifications are usually ____ mm in size and have a variety of sizes and shapes
<0.5
Likelihood of malignancy is about 30%
Distribution of calcification:
a. Distribution of calcifications that has the lowest correlation with malignancy
b. Refers to when calcifications occupy a large area that is more than one ductal system
c. Refers to when calcifications occupy a small area, usually within 2 cm
d. Refers to when calcifications appear wedge shaped with the broad base closer to the chest wall and tapering toward the nipple; These calcifications span more than half the distance from the chest wall to the nipple.
a. Diffuse
b. Regional
c. Grouped
d. Segmental
Describe the morphology
ine Linear or Fine Linear Branching Calcifications
Most worrisome of calcification distribution descriptor with likelihood of malignancy of 62%
Segmental
Also known as large rod-like calcifications which are benign calcifications of the duct. Branching pattern is common. They are smooth and cigar shaped. They are most often diffuse, bilateral, and seen almost exclusively in postmenopausal women.
Secretory calcifications
Benign or malignant?
Benign
Popcorn calcifications commonly seen in involuting or degenerating fibroadenomas
The following are considered benign calcifications, except:
a. Round
b. Popcorn
c. Rim
d. Coarse heterogeneous
d. Coarse heterogeneous
These eggshell calcifications are often seen in:
a. Oil cysts
b. Fat necrosis
c. Both
d. Neither
c. Both
29/F with history of breast trauma. Describe the calcification
Dystrophic calcifications
The following can present with architectural distortion, except:
a. Prior surgery
b. Trauma
c. Fibrosis
d. Radial scar
e. AOTA are causes
e. AOTA are causes
Most suspicious type of asymmetry
Developing asymmetry
It is new or larger when compared to priors (Fig. 21.38). It has the highest association with malignancy—with a PPV of approximately 12.8% at screening and 26.7% at diagnostic mammography
This margin descriptor is unique to ultrasound. The edges of the mass are forming acute angles or tail-like extensions. This can signify extension of the mass from a milk duct.
Angular
Which of the following has the highest associated with malignancy?
a. Simple cyst
b. Clustered microcysts
c. Complicated cysts
d. Complex cystic and solid mass
