To evaluate the ultrasonographic and mammographic characteristics of sclerosing adenosis (SA)
and compare the diagnostic accuracy of the two radiological methods.
Methods:
Imaging characteristics of 151 lesions pathologically confirmed as SA were reviewed. All the lesions were graded by Breast Imaging Reporting and Data System (BI-RADS).
Results:
A total of 151 lesions were found in 145 patients. All the patients underwent ultrasonography
and imaging findings were as follows: heterogeneously echogenic areas in 9.3% (14/151)
mass lesions in 65.6% (99/151)
focal acoustic shadowing in 4.0%(6/151)
and negative in 21.2% (32/151). A total of 136 patients underwent mammography
and imaging finding
s were as follows: microcalcifications in 31.6% (43/136)
masses in 23.5% (32/136)
asymmetric focal density in 14.7% (20/136)
focal architectural distortion in 22.8% (31/136)
and negative in 7.4% (10/136). Comparing BI-RADS category with histopathology
the accuracy of ultrasonography was higher than mammography (53.6% vs. 40.4%).
Conclusion:
There are no specific imaging characteristics of SA
and further studies about this disease are needed.
