Analysis of clinical mammography of breast calcification for diagnosis of benign and malignant diseases:a report of 380 cases
Objective To analyze the nature and mammography of breast calcification,so as to provide the best clinical treatment plan for clinic.Methods Retrospective analysis was performed on the clinical data of 380 patients with breast diseases confirmed by puncture,Mammotome and surgical clinicopathology and with complete data,all cases were examined by mammography,and a retrospective and comprehensive analysis was performed to analyze the shape,margin,size,density,number,distribution and image changes of the surrounding tissues of calcification.Results 380 cases in this study,there were 296 cases of benign calcification,accounting for 78%,including 41 cases of fibrocystic change,69 cases of milk duct calcification,17 cases of vascular calcification,3 cases of sebaceous gland calcification,3 cases of lipoma,4 cases of surgical suture calcification,3 cases of traumatic scar calcification,2 cases of hemorrhagic mechanism,68 cases of nodular calcification,14 cases of degenerative change and 72 cases of fibroadenoma.There were 84 cases of malignant calcification,accounting for 22%,among which 56 cases of infiltrating ductal carcinoma,18 cases of medullary carcinoma,6 cases of infiltrating lobular carcinoma and 4 cases of cystadenocarcinoma.Breast calcification was divided into intra-glandular tissue calcification and extra-glandular tissue calcification,with 345 cases of intra-glandular tissue(within ducts or lobular follicles)calcification and 35 cases of extra-glandular tissue calcification,including 17 cases of vascular calcification,3 cases of traumatic scar calcification,4 cases of surgical suture calcification,7 cases of cyst of galactostasia,3 cases of sebaceous gland calcification,and 3 cases of lipoma.Patchy,punctate calcifications with high density and well-defined margins;mud-like,acicular worm-like calcifications with low density and poorly defined margins;circular,double-track-like calcifications with a fixed shape.Conclusion The analysis of benign and malignant breast calcification signs is of great clinical significance for the diagnosis and differential diagnosis of benign and malignant breast lesions,especially for the early diagnosis and treatment of micro-breast cancer and ductal infiltrating carcinoma.w
