A. Postoperative seroma

B. Fat necrosis

C. Recurrent tumor

D. Flap edema

28a

B. Fibroadenoma

C. Invasive ductal carcinoma

D. Phyllodes tumor

E. Simple cyst

28b
 What are the typical MRI features of this mass, if this patient had a breast MRI done?

A. Enhancing mass with nonenhancing internal septations

B. Low T1-weighted and high T2-weighted signal intensity with no enhancement

C. Multiple small fluid intensity components within a heterogeneous mass

D. Type 3 enhancement kinetic curve

E. Signal loss on fat-saturated sequences

29
 Which benign lesion is most likely to demonstrate a classically malignant characteristic on MRI?

A. Fibroadenoma

B. Fat necrosis

C. Simple cyst

D. Hamartoma

30a

D. 15%

34
 Calcifications are seen on a poststereotactic biopsy radiograph of the specimen. However, the pathologist states no calcifications are seen in the specimen provided. What is the next BEST step?

A. Accept the pathology results.

B. Recommend 6-month follow-up mammogram.

C. Analyze specimen using polarized light microscopy.

D. Recommend rebiopsy.

35
 You are shown a screening mammogram and CC and MLO projection magnification views. What is the MOST appropriate BI-RADS designation?
