Treatment of Inverted Nipple with Subareolar Abscess : Usefulness of High-Resolution MRI for Preoperative Evaluation

Abstract EN

Background.

Inverted nipples with subareolar abscesses can recur due to insufficient resection.

It is important to provide reliable curative treatment after determination of the extent of resection by preoperative imaging evaluation.

Methods.

Ten patients were treated for inverted nipples with subareolar abscess.

Sonography and high-resolution MRI were used as preoperative imaging modalities.

The endpoints of preoperative imaging evaluation were defined as the identification of the abscess site, isolated fistula site, and extent of inflammation.

Results.

In all patients, sonography confirmed the presence of abscesses but their locations could not be identified.

Sonography could not confirm the presence of isolated fistula or inflammation.

In contrast, high-resolution MRI not only confirmed the presence of abscesses but also revealed their positional relationships with the nipples.

In addition, high-resolution MRI confirmed the presence of isolated fistulas and inflammation as well as revealed their positional relationships with the nipples.

In all patients, no recurrence was observed, and satisfactory surgical results were obtained.

Conclusion.

High-resolution MRI is useful in determination of the extent of resection of subareolar abscess associated with inverted nipple.
