| Purpose: The purpose of this study was to evaluate the B-mode sonographic and
sonoelastographic features of high risk lesions of the breast.
Materials and Methods: From April 2009 to February 2010, 1390 patients with
breast lesions underwent US-guided core-biopsy. Among them, 13 lesions were confirmed
to be pure sclerosing adenosis by subsequent surgical excision or on imaging
follow-up of more than 1 year. Two radiologists retrospectively analyzed the B-mode
sonography according to the Breast Imaging Reporting and Data System classification.
The sonoelastographic images were classified into 5 elasticity scores according
to the Itoh classification and the strain ratio between the mass and the surrounding fat
tissue was reviewed. We considered the sonoelastographic patterns to be suspicious
for the case with a score of 4 and 5 and a strain ratio of more than a 2.24.
Results: The common B-mode sonographic features of sclerosing adenosis were
an irregular shape (69.2%, 9 of 13), an indistinct margin (92.3%, 12 of 13), hypoechogenicity
(76.9%, 10 of 13) and category 4A, a low suspicion of malignancy (61.5%,
8 of 13). The common sonoelastographic features were a score of 2 (42%, 6 of 13)
and a strain ratio < 2.24 (69.2%, 9 of 13).
Conclusion: Sclerosing adenosis showed suspicious B-mode sonographic findings,
but it had benign sonolastographic features. |
