Purpose: To describe mammographic and ultrasonographic findings of previous
chemoport insertion sites.
Materials and Methods: We included patients who had abnormal findings at
chemoport insertion sites on mammography and ultrasonography from 224 patients
who underwent chemoport insertion and breast imaging at our institution between
January, 2005, and December, 2007. Abnormal findings were identified in 16 mammographies
and 14 ultrasonographies in 10 patients. The mean age was 50.9 years
and the age range was from 44 to 67 years. Abnormal findings on mammography and
ultrasonography were retrospectively analyzed according to ACR/BI-RADS. All cases
were followed up with imaging studies for 2 years to confirm changes after chemoport
insertion.
Results: Of the abnormal findings identified on mammography, focal asymmetry
(7/16) was the most common. Other abnormal findings included mass (6/16), skin
retraction (2/16), residual chemoport tip (1/16), and trabecular thickening (1/16). Of the
abnormal findings seen on ultrasonography, skin thickening (12/14) was the most
common. Other abnormal findings included mass (5/14), diffuse increased echogenicity
of subcutaneous tissue (1/14), and a localized skin nodule (1/14). Abnormal findings
on mammography and ultrasonography were located in the upper outer quadrant
in 5 patients, upper inner quadrant in 3 patients, and mid upper portion in 1 patient. In
1 patient, the abnormal finding was only identified in the mediolateral oblique view of
her mammography.
Conclusion: Radiologists should be aware of potential abnormal findings on mammography
and ultrasonography following chemoport insertion. In particular, ultrasonography
is a very useful modality for detecting skin complications after chemoport
insertion. |
