A 48-year-old woman undergoes diagnostic mammography for a palpable lump. A round, circumscribed, 1.5 cm mass is seen corresponding to the area of palpable concern. Ultrasound confirms a simple cyst. What is the correct BI-RADS assessment?
- A BI-RADS 2 ✓
- B BI-RADS 1
- C BI-RADS 3
- D BI-RADS 4
Correct answer: A. BI-RADS 2
Explanation
B simple cyst on ultrasound is a benign finding with 0% malignancy rate. When a palpable lump corresponds to a simple cyst, BI-RADS 2 (benign) is appropriate. BI-RADS 1 is used when the examination is entirely normal with no findings. BI-RADS 3 is for probably benign solid masses. B simple cyst is definitively benign, warranting BI-RADS 2 and reassurance.
