Learning objectives: ♠The purpose of our educational exhibit is to: Review key anatomical structures, pathologic mechanism and clinical implication of papilledema Describe the key MRI findings of papilledema Review several causes of increased intracranial pressure and  papilledema, with some cases. Emphasize [...]

Background: 1. Definition of papilledema  Optic disc swelling associated with increased intracranial pressure (ICP) 2. Fundoscopic findings of papilledema (Fig.1) Optic disc swelling with blurred margin Disc hyperemia Peripapillary hemorrhage Venous engorgement 3. Key anatomic structures associate[...]

Findings and procedure details: ♠ Key MR imaging findings of papilledema 1. Widening of optic nerve sheath Normal optic nerve sheath - Diameter      Just behind the globe: 5.52 ± 1.11 mm     4 mm posterior to the globe : 5.2 ± 0.9 mm Bulbous appearance at just behind the globe  - Most di[...]

Conclusion: ♠ Summary Papilledema is optic disc swelling associated with intracranial pressure (ICP) Early detection of papilledema is important because it could be indicator of increased ICP and could lead to visual impairment and even blindness by itself There are some key MRI findings which represent th[...]
