| Purpose: To verify the role of additional sonography on routine mammograms in
the diagnosis of ductal carcinoma in situ (DCIS).
Materials and Methods: Between 2005 and 2008, a total of 105 breasts belonging
to 102 patients were diagnosed with DCIS by surgery. Preoperative ultrasound and
mammographic findings and reports using BI-RADS were retrospectively reviewed
and analyzed. In both mammogram and ultrasound, BI-RADS categories 1, 2, and 3
were regarded as negative results and categories 4 and 5 as positive results. We analyzed
the frequency in which additional ultrasound examinations aided in the diagnosis
in each mammographic finding.
Results: Out of the 105 cases, 96 showed positive results on a mammogram and 9
cases showed negative results. Clustered microcalcifications, positive mammographic
findings, were found most often (64/96, 66.67%). In those cases, ultrasound examinations
gave no additional information, but did enablesonographically-guided biopsies in
38. In the 32 cases with other positive mammographic findings, ultrasound examinations
were helpful in 15 cases. Of the 9 cases showing negative results on a mammogram,
8 cases were correctly diagnosed with DCIS because of the additionally-performed
ultrasound examination, but 1 case returned a false negative on both the
mammogram and ultrasound examination.
Conclusion: Additional sonography contributes to a diagnosis of DCIS in patients
with negative mammographic findings, nonspecific mammographic findings, or multifocal
lesions. |
