Basilar artery thrombus with near total occlusion.
From the case:
Hyperdense basilar tip 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/123969/annotated_viewer_json?lang=us"}
The thrombus of the distal basilar artery nearly completely fills the vessel.
