Targeted ultrasound of the right axillary region is requested. A targeted right ultrasound was performed in the axillary tail and axilla. There is suspicious no solid or cystic mass identified. Two mixed echogenicity areas are identified. One is in the right axillary tail region, and the other more truly in the axilla. It is likely that the axillary finding on this exam correlates with mammography. This measures up to 2.8 x 1.9 cm, similar to prior measurements allowing for differences in positioning and axis of measurement.
Mixed echogenicity area in the right axilla correlates with mammography. Based on the mixed echogenicity and clear areas of fat within this finding on the mammogram, this is highly compatible with accessory axillary breast tissue or hamartoma. A 6 month follow-up can be considered presuming physical exam is benign.BIRADS: 3 - Probably benign finding.RECOMMENDATION: 3B - Followup at Short Interval (1-11 Months).
