Abstract:
Objective To analyze sonographic characteristics of the automated breast volume scanner (ABVS) in non-mass-like breast carcinoma.Methods 49 patients with non-mass-like breast carcinoma were confirmed by pathology after operation.All of the patients underwent ABVS,the sonographic characteristics of internal echo and microcalcifications in the lesions,the retraction phenomenon in coronal plane and surrounding change were analyzed.All the lesions were assessed by breast imaging reporting and data system (BI-RADS).Results In 49 patients with non-mass-like breast carcinoma,27(55.10％) cases were ductal carcinoma in situ,21 (42.86％) cases were infitrating ductal carcinoma,and 1 (2.04％) case were infitrating lobular carcinoma.The findings of ABVS:43 (87.76 ％) lesions appeared as segmental hypoechoic areas,41 (83.67％) lesions appeared as scattered or clustered microcalcifications,6(12.24％) lesions appeared as the retraction phenomenon in coronal plane,and 1 (2.04％) lesion appeared as pachyderma and subcutaneous dropsy.Microcalcifications in ductal carcinoma in situ appeared more than that in infitrating ductal carcinoma (85.19 ％ vs 80.95 ％,P =0.715) ;the retraction phenomenon in coronal plane of infitrating ductal carcinoma were higher than that of ductal carcinoma in situ(19.05％ vs 7.41％,P =0.383),but there were no significant difference in those between ductal carcinoma in situ with infitrating ductal carcinoma(P ＞0.05).All the cases were assessed according to BI-RADS,including 4a-5 category 44 cases,0-2 category 5 cases.The coincidence rate in diagnosis of ABVS were 89.80％.Conclusions The ABVS features of non-mass-like breast carcinoma are characteristic.Segmental hypoechoic areas,microcalcifications and the retraction phenomenon in coronal plane are important for the diagnosis of non-mass-like breast carcinoma,ABVS can improve the detect ability and decrease the missed diagnosis of non-mass-like breast carcinoma.
