| Purpose: The purpose of this study was to evaluate the usefulness of sonographic
BI-RADS in differentiation between benignity and malignancy of complex breast cysts.
Materials and Methods: Among 855 female patients who underwent ultrasoundguided
core needle biopsy at our hospital from March 2012 through August 2012, 82
pathologically proven complex cysts detected on ultrasonography were included. The
BI-RADS classification was made by radiologists prospectively and the imaging characterization
of cystic lesions were classified retrospectively as cystic masses with a
thick septa or thick wall, mixed solid and cystic masses, or solid masses with eccentric
cystic foci. All lesions examined by ultrasonography were classified prospectively
according to the BI-RADS lexicon. The pathologic findings were compared with sonographic
appearance. We reviewed and compared the radiologic features between
malignant lesions and benign lesions.
Results: Finally, according to biopsy results, there were 71 benign and 11 (13.4%)
malignant lesions. The frequency of malignancy was significantly higher in solid masses
with eccentric cystic foci (p value <0.025). The size of sonographic lesions was significantly
larger in malignant lesions than in benign lesions (41.82 mm±34.36 vs
18.41 mm±16.8 respectively, p=0.049). No statistically significant difference was
observed in the sonographic findings according to the BI-RADS lexicon, however, statistically
significant difference in final assessment categories was observed between
benign and malignant lesions (p value <0.001).
Conclusions: The malignancy rate was higher in cystic lesions with predominantly
solid masses and classified as suspicious malignancy using the BI-RADS lexicon. |
