Presentation
Left weakness and dysphasia for 3.5 hours.
Patient Data
Age: 40 years
Gender: Male
From the case:
Anterior cerebral artery territory infarct
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_pin":false},"extraPropsURL":"/studies/41581/annotated_viewer_json?lang=us"}
Grey-white differentiation is preserved. Hyperdense right anterior cerebral artery, with filling defect of the the right A1 segment and subtle under-filling of the A2 segment on CTA.
Fat density lesion within the right posteriorly paravertebral space likely represents lipoma.
From the case:
Anterior cerebral artery territory infarct
{"current_user":null,"step_through_annotations":true,"access":{"can_edit":false,"can_download":true,"can_toggle_annotations":true,"can_feature":false,"can_pin":false},"extraPropsURL":"/studies/41584/annotated_viewer_json?lang=us"}
Restricted diffusion confined to the right anterior cerebral artery territory is present consistent with infarction.
Case Discussion
ACA territory infarcts are much less common than MCA territory infarcts. Cardio-embolic events are the most common cause.
