Case 102
Case History
A 39-year-old woman presents with a right breast palpable lump. She is 6 months post-partum and is still breast-feeding. She was initially studied with lower-frequency sonography (Fig. 102–2). Her sonogram was interpreted as BI-RADS Category 3 (probably benign lesion, short-term follow-up recommended). After 1 month, because symptoms persisted, she was examined with high-frequency sonography (Fig. 102–3). As a result of her high-frequency sonogram, mammograms were performed (Fig. 102–1).
