From the case:
Empty sella
{"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/141470/annotated_viewer_json?_c=1695579704\u0026lang=us"}
Expanded pituitary fossa, filled with fluid of CSF signal. The infundibulum traverses the sella with no significant displacement " infundibulum sign", well-demonstrated on postcontrast sequences.
Case Discussion
MRI features in keeping with empty sella.
There are two categories of empty sella:
complete/total empty sella: >50% of the sella filled with CSF; pituitary thickness ≤2 mm (as in this case, the pituitary thickness was 1.6 mm)
partial empty sella: <50% of the sella filled with CSF; pituitary thickness ≥3 mm
