1. Develop a clear understanding of the anatomy of the retroperitoneum. 2. Provide an appropriate approach to imaging evaluation of retroperitoneal masses. 3. Demonstrate imaging features on different modalities (ultrasound, CT and MRI) that can allow the radiologist to determine the origin of a mass. 4. Review the imaging features of benign versus malignant masses. 5. Cover important pitfalls that radiologists should be aware of when evaluating masses in the retroperitoneum.

Anatomic Review of the Retroperitoneum Appropriate Imaging Evalution of Retroperitoneal Masses Determining the Site of Origin of Retroperitoneal Masses Differentiating Benign vs. Malignant Features to Consider: (1) Fat content, (2) Necrosis, (3) Cystic content, (4) Vascularity, (5) Margins, (6) Degree of invasion, (7) Clinical History / Prior studies Sample cases and mimics Future directions / Teaching Points / Summary
