Purpose : The purpose of this study was to assess the mammographic features and
pathologic outcome of category 4 lesions using the Breast Imaging Reporting and Data
System(BI-RADS), and to evaluate the significance of final assessment categories.
Materials and Methods : Using BI-RADS, the interpretations of 8,134 mammograms
acquired between January 1997 and May 1998 were categorized. From among 161 lesions
categorized as '4' ('suspicious abnormality') and pathologically confirmed by surgery
biopsy, we analysed 113, found in 66 patients.
Result : The pathologic outcome of these 113 lesions was as follows: infiltrating ductal
carcinoma, 17.7%(20/113); DCIS(ductal carcinoma in sitv), 8.0%(9/113); ADH(atypical
ductal hyperplasia), 5.3%(6/113); DEH(ductal epithelial hyperplasia), 1.8%(2/113);
ductectasia, 0.9%(1/113), FCA(fibrocystic change), 27.4%(31/113); fibroadenoma,
7.1%(8/113); stromal fibrosis, 9.7%(11/113); normal parenchyma, 7.1%(8/113); other
pathology, 15.0%(17/113). The most frequent mammographic features of BI-RADS
category 4 lesions were irregular mass shape(41.2%), spiculated mass margin(52.3%),
amorphous calcification(47.3%) and clustered calcification distribution(37.1%).
Conclusion : Because category 4 lesions account for about 25.7% of all breast
malignancies, mammographic lesions in this category ('suspicious abnormality') should
be considered for supplementary study and breast biopsy rather than short-term
follow-up. Initial pathologic findings can thus be confirmed.
