Comparative analysis on ultrasonic and mammographic characteristics of breast chronic inlfammation / 中华医学超声杂志（电子版）

ABSTRACT

Objective To compare the ultrasonic and mammographic appearances of breast chronic inflammation (BCI). Methods The ultrasonic and mammographic features of 20 pathologically conifrmed BCI cases were analyzed retrospectively. All cases were of single lesion. Fisher deifnite probability method was used to compare the differences between ultrasonic and mammographic appearances as well as the diagnostic coincidence rate. Results Under ultrasonography, the mean longitudinal diameter/transverse diameter (L/T) ratio of 20 lessions was calcultated as 0.47±0.15, 17 lesions were of irregular shape, unclear boundary and inhomogeneous hypoecho, 13 lesions were of posterior echo enhancement, the blood lfow of 10 lesions belonged to 0-Ⅰ, and the other 10 belonged toⅡ-Ⅲ. The lesion shape, boundary and homogeneity detected by mammography were coincident to those by ultrasonography (P=1.00, 1.00, 0.61, respectively). In 5 lesions, dotted high-echoes were detected by ultrasonography, however no calciifcation was found by mammography. Meanwhile, 1 lesion with sporadic calciifcation detected by mammography was missed by ultrasonography. Ultrasonography detected 5 cases with axillary lymphadenopathy, in which only 1 case was found by mammography. The diagnostic coincidence rate of ultrasonography was 40%(8/20), which was obviously higher than 6% (1/16) by mammography (P=0.03). Conclusion BCI possesses certain ultrasonographic characteristics, and ultrasonography combined with mammography will be helpful for the differential diagnosis of malignant and benign diseases.
