The purpose of this exhibit is: 1. To review pertinent anatomy and anatomic relationships of the orbit 2. To review MR imaging characteristics of neoplasms affecting the orbits, as well as differentiating features from lesions that mimic neoplasm 3. To describe common pathways of spread of orbital neoplasms

Basic Anatomy  - Contents of the orbit  - Osseous boundaries of orbit  - Intraconal, Conal, and Extraconal spaces  - Foramina relating spread of pathology (including superior orbital fissure, inferior orbital fissure)  Sample cases with explanation of pertinent MR imaging characteristics:  - Orbital MALT lymphoma  - Meningioma  - Metastatic disease  - Orbital Pseudotumor  - Orbital dermoid Conclusion  - Key features of neoplasms involving the orbit and their differentiating MR imaging characteristics
