Objective: The objective of this article is to describe the types of breast emergencies that can be encountered in a breast imaging practice, discuss the characteristic imaging features of these emergencies, and explain the most common methods and interventions used for the treatment of breast emergencies and complications.
Conclusion: Breast emergencies are uncommon but require prompt identification and management when they do occur. Patients with mastitis or a breast abscess may be seen for either diagnosis or treatment. Most complications are the result of interventional procedures. Pseudoaneurysms, postbiopsy hematoma, and localization wire migration are the most common situations encountered. A milk fistula resulting from a core biopsy is uncommon. Fortunately, seat-belt injuries to the breast are rare. Knowledge of these entities--of the usual presentation, management, and appropriate follow-up protocols--is essential for breast imagers.
