Background
Masses that appear cystic on ultrasound are commonly found and have a wide array of pathologies. This includes the benign simple cyst requiring no follow up, to the complex cystic and solid mass found to represent a breast cancer. As cystic lesions are often benign, it is important to recognize the subtle suspicious imaging features that will require biopsy, so cancer is not missed. It is also important to recognize always benign and commonly benign features to prevent unnecessary biopsy, which can be stressful for the patient and occasionally result in a biopsy complication.
Educational Goals / Teaching Points
The purpose of this exhibit is to review the imaging findings and management of cystic breast lesions using descriptors from the BI-RADS 2013. Differential diagnosis and pathology will be discussed to assist in understanding the pathologies that can appear cystic, as well as how to manage the imaging findings. The overall goal for improved understanding of cystic breast lesions is to avoid unnecessary biopsy and not miss cancer.
Key Anatomic/Physiologic Issues and Imaging Findings/Techniques
This exhibit will characterize and classify cystic breast masses using ultrasound and mammography. BI-RADS terminology will be used to describe the masses and understand the best follow-up or management of each lesion type. Management will also be discussed, including pathologic diagnosis for masses that underwent biopsy.
Conclusion
At the conclusion of the exhibit, the learner should feel more comfortable with the approach to cystic breast lesions to avoid unnecessary biopsy and prevent missed cancer.
