Correlation of ultrasonographic types of breast fibroadenomas with pathologic findings / 中华超声影像学杂志

ABSTRACT

Objective To explore the correlation of ultrasonographic,pathologic,and clinical findings of breast fibroadenomas.Methods 157 cases of breast fibroadenomas demonstrated by pathologic findings were examined with color Doppler ultrasound prior to biopsy.Images were classified according to ultrasound characteristics and analysed with latter pathologic findings.Results Ultrasound images of 157 cases could be divided into 6 typesuniformity( n =82),linage( n =37),bicolor( n =15),nodule-in-nodule (n =3),cyst-massity mixed ( n =9),calcify( n =11).5 cases were mistakenly judged to breast cancer on ultrasound images(1 ease in the linage,1 case in the cyst-mass mixed,3 cases in the calcify).Accurate ratio of ultrasound diagnosis was 96.82％.Pathologic finding:①Uniformity type,hyperplasia of both the gland and fibrous tissue of tumor in order.② Linage type,hyperplasia fibrous tissue in belt.③ Bicolor type,significant difference in the proportion and arrangement of the hyperplasia gland and fibrous tissue.④Nodule-in-nodule type,extensive hemorrhagic infarction in tumor.⑤Cyst-massity mixed type,hydatoncus,metaplasia in great sweat gland,hyperplasia conduit epithelial,conduit cystic-expansion.⑥ Calcify type,fibroadenomas on growth of static or regression transformation,and calcify of interstitial tissue.Conclusions Ultrasonic diagnosis and its simple typing is an accurate,simple and effective way for the diagnosis of breast fibroadenoma,which may improve the accuracy of diagnosis rate for breast fibroadenoma.It is helpful for choosing the surgical remedies.
