The ultrasonographic characteristics of fibrocystic breast change / 中华超声影像学杂志

ABSTRACT

Objective To investigate the ultrasonographic features of fibrocystic breast change ( FBC) and improve the ultrasonographic diagnosis and differential diagnosis of FBC . Methods Fifty‐five patients of FBC with 60 lesions and 39 patients of invasive ductal carcinoma ( IDC ) with 42 lesions ,which were confirmed by pathology after operation in the Affiliated Union Hospital of Fujian M edical University from January 2014 to February 2019 were enrolled . T he preoperative sonographic findings of FBC and IDC were retrospectively analyzed and compared . Results T here was no significant difference between the two groups in the rates of showing irregular shape ,which were 86 .7% in FBC group and 88 .1% in IDC group , respectively ( P ＞0 .05) ,but the rate of showing crab feet or burrs on the edge of lesions in FBC group was lower than that in IDC group( P ＜0 .05 ) . T he occurrence rates of posterior echo enhancement and cystic degeneration in FBC group were 81 .7% and 71 .7% respectively ,w hich were significantly higher than those in IDC group ( 38 .1% and 16 .7% ) ( P ＜0 .001) . In addition ,the FBC group showed fewer features such as hyperechoic halo and more features such as hypovascular supply than that of IDC group ( all P ＜0 .001 ) . Conclusions In terms of ultrasonic features ,including irregular shape or even crab feet and burrs ,FBC can be easily misdiagnosed as malignant tumors . However ,posterior echo enhancement ,interior scattered small cysts ,lack of blood supply and rare hyperechoic halo may be the characteristics of FBC ,w hich can be differentiated from malignant tumors .
