| Abstract: |
| Objective The aims of this study were to analyze ultrasound features of breast ductal carcinoma in situ
(DCIS) and to evaluate the value of ultrasonography (US) in early diagnosis of DCIS.
Methods From July 2013 to March 2015, 180 patients with histologically proven DCIS were evaluated.
US features recorded included the size, shape, margins, internal echogenicity, microcalcifications, posterior
echogenicity, and blood supply. The data were analyzed and compared with mammographic and histologic
findings.
Results Among 180 cases of DCIS, 168 patients had positive findings on US; the lesions were divided
into 3 categories: (1) hypoechoic lesions with or without microcalcifications (n=94); (2) hypoechoic dilated
ducts with or without microcalcifications (n=59); (3) microcalcifications alone without any other findings
(n=15). Of the 180 lesions, microcalcifications were demonstrated by mammography in 128 (71%); among
these 128 lesions, 90 were identified with microcalcifications on US. Only 80 cases (44%) manifested as
masses or asymmetric densities on mammography. The diagnostic accuracy of US and mammography
was 67% (120/180) and 69% (124/180), respectively, which can be improved to 80% (144/180) if US is
combined with mammography.
Conclusion US can be used as an important tool in diagnosis of DCIS. The combination of US and
mammography can improve the diagnostic accuracy of breast DCIS. |
