Background Information: A shrinking breast has been usually attributed to a malignant cause, but in the postsurgical setting evolving fat necrosis should be considered. The purpose of this exhibit is to review and discuss benign etiologies of a shrinking breast as well as its mammographic and sonographic presentations.

Educational Goals/Teaching Points: This exhibit will present a review of benign and malignant etiologies of a shrinking breast and review mammographic and sonographic features of a shrinking breast in accordance to its cause. We discuss the imaging management algorithm of a shrinking breast and indications for percutaneous biopsy.

Key Anatomic/Physiologic Issues and Imaging Findings/Techniques: Mammographic findings, breast ultrasound findings, percutaneous imageā€“guided needle biopsy findings are presented.

Conclusion: Understanding the clinical context in which a shrinking breast develops, its imaging features, and indications for biopsy and surgery will allow proper accurate diagnosis.
