From the case:
Spondylolisthesis - distended facet sign
{"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/11250/annotated_viewer_json?_c=1699857815\u0026lang=us"}
MR demonstrates the "distended facet sign" at L4-5. It implies the presence of spondylolisthesis (with or without lysis).
Case Discussion
The abnormal range of movement at the facet joints in the supine non-weight-bearing position results in fluid distension which would disappear on weight-bearing.
