The purpose of this exhibit is to familiarize the viewer with the CT and MR appearance of gynecomastia, which is a benign and common entity that may be incidentally identified in a wide range of patients. The body imager should be aware of the various appearances of this entity and not confuse it for a malignant lesion. We will: 1. Review the clinical features of gynecomastia, including presentation and risk factors. 2. Review the mammographic and sonographic appearance of the three patterns of gynecomastia. 3. Demonstrate the CT and MRI appearance of gynecomastia, with correlation to mammographic appearance. 4. Note cases in which this incidentally imaged entity may be safely considered benign, and requires no further imaging.
