Abstract:
Objective To explore the characteristic manifestations of breast malignant isodense masses using mammography. Methods 121 breast isodense masses with pathological confirmations were collected.Compared indicators with pathological findings were the tumor size,shape,edge,structure changes around the mass,axillary lymph nodes,skin changes,nipple changes,suspi-cious malignant calcification.χ2 test and Logistic regression analysis were used to evaluate the diagnostic values of each indicator.Re-sults In the 121 isodense masses,73 were benign,48 were malignant tumors.According to χ2 test analysis,factors impacted the nature of mass including:tumor morphology (χ2 =14.376,P =0.002),tumor edge (χ2 = 21.555,P =0.000),structure twisted surrounding the mass (χ2 =26.939,P =0.000),axillary lymph nodes (χ2 =1 6.285,P =0.000),skin thickening (χ2 =4.698,P =0.030).According to multivariate binary Logistic regression analysis,risk factors of the Logistic regression model included:edge infiltrating of mass (P =0.014),structure twisted surrounding the mass (P =0.003),axillary lymph nodes (P =0.026).Conclusion The characteristic manifestations of breast malignant isodense masses include edge infiltrating,structure twisted surrounding the mass,axillary lymph nodes.These manifestations are of great significance in differential diagnosis of breast isodense masses.
