Fig. 1A 50-year-old woman who underwent evaluation of questionable
density in outer aspect of left breast visible only on craniocaudal
mammographic views and not identified sonographically. Sagittal
contrast-enhanced dynamic MR image of breast in maximum slope in first minute
after contrast injection (TR/TE, 9/4; slice thickness, 4.0 mm; interslice gap,
4.0 mm; field of view, 22 cm) shows 9-mm lobulated mass (arrow) in
upper outer aspect of left breast. Results of dynamic time-intensity analysis
were consistent with findings at fast initial enhancement and delayed plateau
(not shown).

Fig. 1B 50-year-old woman who underwent evaluation of questionable
density in outer aspect of left breast visible only on craniocaudal
mammographic views and not identified sonographically. Axial 3D fast imaging
employing steady-state acquisition (FIESTA) image of breast (TR/TE, 4/1; slice
thickness, 5.0 mm; interslice gap, 5.0 mm, matrix size, 256 x 256; field
of view,16 cm) after insertion of needle shows needle (white arrows)
localizing region of targeted lesion according to x, y, and
z coordinates and anatomic landmarks (not shown). Changes associated
with injection of local anesthesia (black arrows) at skin entry are
evident.

Fig. 1C 50-year-old woman who underwent evaluation of questionable
density in outer aspect of left breast visible only on craniocaudal
mammographic views and not identified sonographically. Whole-specimen
radiograph shows targeted lesion at thickened segment (arrows) of
intact hookwire. S = superior, L = lateral.

Fig. 1D 50-year-old woman who underwent evaluation of questionable
density in outer aspect of left breast visible only on craniocaudal
mammographic views and not identified sonographically. Sliced-specimen
radiograph shows irregular, spiculated mass (arrows) excised with
acceptable surgical margins. Image shows only sections of sliced-specimen
radiograph that contain excised lesion and surrounding margins. All specimen
margins are clear of tumor. A = anterior, P = posterior, M = medial.

Fig. 1E 50-year-old woman who underwent evaluation of questionable
density in outer aspect of left breast visible only on craniocaudal
mammographic views and not identified sonographically. Histopathologic image
shows moderately differentiated invasive ductal carcinoma (arrow) and
intermediate-grade ductal carcinoma in situ (arrowhead) infiltrating
around adenosis. Tumor measured 0.9 cm; minimum 1-cm negativity of all margins
was verified. (H and E, x100)

Fig. 2A 45-year-old woman with history of cancer of left breast and
segmental mastectomy who underwent evaluation of palpable area in 6-o'clock
position of left breast. Mammographic and sonographic findings were normal.
Sagittal contrast-enhanced dynamic MR image obtained in maximum slope in first
minute after contrast injection (TR/TE, 9/4; slice thickness, 4.0 mm;
interslice gap, 4.0 mm; field of view, 22 cm) shows spiculated mass
(arrow) with heterogeneous enhancement in left breast suspicious for
malignancy according to morphologic findings. Results of dynamic
time-intensity curve analysis (not shown), which is also suspicious for
malignancy, were consistent with rapid wash-in and subsequent early
washout.

(TR/TE, 4/1; slice thickness, 5.0 mm, interslice gap, 5.0 mm; matrix size, 256

Fig. 2C 45-year-old woman with history of cancer of left breast and
segmental mastectomy who underwent evaluation of palpable area in 6-o'clock
position of left breast. Mammographic and sonographic findings were normal.
Whole-specimen radiograph shows mass (arrows) with adjacent intact
hookwire at periphery of specimen. L = lateral, S = superior, I = inferior, m
= medial.

Fig. 2D 45-year-old woman with history of cancer of left breast and
segmental mastectomy who underwent evaluation of palpable area in 6-o'clock
position of left breast. Mammographic and sonographic findings were normal.
Sliced-specimen radiograph shows dense oval mass (arrows) with
inconspicuous margins at superior lateral margin of excised tissue sample.
Markers show 3D orientation to specimen. Markers indicating medial and lateral
margins are not shown. P = posterior, S = superior, A = anterior.

Fig. 2E 45-year-old woman with history of cancer of left breast and
segmental mastectomy who underwent evaluation of palpable area in 6-o'clock
position of left breast. Mammographic and sonographic findings were normal.
Photomicrograph shows cauterized invasive and in situ carcinoma involving
inked lateral margin (arrows) of resection. Additional excised tissue
had evidence of malignancy. At mastectomy 6 weeks after this image was
obtained, no residual tumor was identified in mastectomy specimen. (H and E,
x100)
