13-year-old female with bilateral fibroadenomas; clinical decrease in size of the right breast mass with increase in size of the known left breast mass. On physical examination, an additional mass is noted within the lower left breast. Ultrasound is requested for characterization of the new left breast mass, and to demonstrate stability of the known bilateral masses. A targeted left ultrasound was performed for the palpable areas of concern. At the one o'clock position of the left breast, 3 cm from the nipple, there is redemonstration of a parallel, circumscribed oval hypoechoic mass measuring 2.1 x 0.9 x 2.2 cm (previously 1.1 x 0.5 x 1.1 cm). This mass demonstrates mild peripheral vascularity. At the 6 o'clock position of the left breast, 5 cm from the nipple, there is a parallel, circumscribed, oval hypoechoic mass measuring 1.7 x 0.7 x 1.4 cm. The mass demonstrates increased vascularity.A targeted right ultrasound is performed for the palpable area of concern. At the 10 o'clock position of the right breast, 2 cm from the nipple, there is a 1.5 x 0.6 x 1.9 cm parallel, macrolobulated hypoechoic mass decreased in size from prior examination (previously 2.1 x 1.2 cm). This mass demonstrates minimal peripheral vascularity.
1. Increase in size of the previously demonstrated mass at the one o'clock position of the left breast, measuring 2.2 cm on today's examination. This finding likely represents a fibroadenoma. 2. New circumscribed hypoechoic mass at the 6 o'clock position of the left breast measuring 1.7 cm. This finding likely represents a fibroadenoma. 3. Decrease in size of the previously identified right breast mass now measuring 1.9 cm, corresponding to biopsy proven fibroadenoma.BIRADS: 2 - Benign finding.RECOMMENDATION: B - Surgical Consultation.
