ABSTRACT

Foreign bodies, such as surgical sponges or drains, are sometimes retained after surgical procedures.1 Retention of a drain in the breast tissue postoperatively is an unusual complication. This report describes two cases of characteristic sonographic findings related to retained silastic drains following breast surgery.

A 44-year-old woman, who had received treatment for a breast abscess 6 months prior, complained of a painful mass in the subareolar area of the left breast. (A) Initial ultrasonogram of the subareolar area of the left breast shows an ill-defined, inhomogeneous, hypoechoic lesion with internal, free-floating debris, which is highly suggestive of an abscess cavity. (B) Follow-up ultrasonogram of a palpable mass after incision and drainage shows an ill-defined, hypoechoic lesion with internal echogenic parallel lines having a reverberation artifact, suggesting a foreign body (arrows). (C) Craniocaudal mammogram reveals a silastic drain in the left subareolar area (arrows).

Mentions: A 44-year-old woman was admitted to our surgery department with a painful mass in the subareolar area of the left breast. The patient had undergone a surgical incision and drainage of a subareolar abscess 6 months prior (Fig. 1A). Following that procedure, she complained of occasional pain in her left breast. There was a hard and fixed mass in the left subareolar area on physical examination. Breast ultrasonography revealed an ill-defined, hypoechoic lesion with tubular-shaped parallel hyperechoic lines and a reverberation artifact, suggesting a retained drain (Fig. 1B). A craniocaudal view of mammographic images of the left breast demonstrated a high density foreign body in the left subareolar area (Fig. 1C). We confirmed the object to be a silastic drain which was then removed by surgical excision. Histopathologic findings showed a granuloma with surrounding minimal foreign body reaction.
