Objective:

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.
