From the case:
Internal carotid artery dissection
{"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/13524/annotated_viewer_json?lang=us"}
Occluded left internal carotid artery with perhaps a faint crescent sign seen on fat saturated T1 images through the neck, although note the mimicking appearance of flow in the adjacent jugular and contralateral ICA.
Case Discussion
Features are consistent with ICA dissection and infarction presumably from artery to artery embolism, rather than occlusion (patchy infarction, not in a watershed distribution).
