I generally recommend a standard protocol which includes spot compression magnification views (CC and Lat) of the lump and ultrasound in addition to the standard CC and MLO views. If the breasts are entirely fat density on standard views, then the spot mags and ultrasound are omitted.
The spot mags in this case were unrevealing. Often, however, these views show an underlying mass or calcifications within a mass. The ultrasound is presented here:
Ultrasound shows a solid mass with small cystic component at the site of palpable abnormality. Because this mass is solid and palpable, it is considered suspicious and a core biopsy should be perfformed.
Ultrasound-guided core biopsy was performed, yielding fibroadenoma.
A six-month follow-up for all benign biopsies is recommended because of the small, but real possibility of sampling error when performing core needle biopsies. A malignancy missed at core sampling should be detected at the 6-month follow-up exam. The follow-up exam should be whichever modality on which the lesion was best visualized (ultrasound in this case).
