OBJECTIVE. The purpose of this study was to evaluate percutaneous imaging-g
uided core biopsy in the assessment of selected palpable breast masses.
MATERIALS AND METHODS. OF 1388 consecutive breast lesions that had percutan
eous imaging-guided core biopsy, 155 (11%) were palpable. Palpable masses r
eferred for percutaneous imaging-guided core biopsy included lesions that w
ere small, deep, mobile, vaguely palpable, or multiple. Biopsy guidance was
sonography in 140 lesions (90%) and ste reotaxis in 15 (10%). Surgical cor
relation or minimum of 2 years follow-up is available in 115 palpable masse
s in 107 women. Medical records, imaging studies, and histologic findings w
ere reviewed.
RESULTS. Or 115 palpable breast masses. 98 (85%) were referred by surgeons
to the radiology department for percutaneous imaging-guided core biopsy and
88 (77%) had percutaneous imaging-guided core biopsy on the dap of initial
evaluation at our institution. Percutaneous imaging-guided core biopsy spa
red additional diagnostic tissue sampling in 79 (74%) of 107 women, includi
ng 57 women with carcinoma and 22 women with benign findings. Percutaneous
imaging-guided core biopsy did not spare additional tissue sampling in 28 w
omen (26%), including 15 women in whom surgical biopsy was recommended on t
he basis of percutaneous biopsy findings and 13 women with benign (n = 7) o
r malignant (n = 6) per cutaneous biopsy findings who chose to undergo diag
nostic surgical biopsy.
CONCLUSION. Percutaneous imaging-guided core biopsy is useful in the evalua
tion of palpable breast masses that are small, deep, mobile, vaguely palpab
le, or multiple. In this study, percutaneous imaging-guided core biopsy spa
red additional diagnostic tissue sampling in 74% women with palpable breast
masses.
