Ecchordosis physaliphora
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_examine_pipeline_reports":false,"can_pin":false},"extraPropsURL":"/studies/17226/annotated_viewer_json?lang=us"}
Bony margins of the defect are smooth, and clearly non-aggressive.
Case Discussion
Absence of enhancement or restricted diffusion together with non-aggressive bony margins in this location is typical of a retroclival ecchordosis physaliphora, a notochord remnant.
