Anterior cerebral artery territory infarct

Case contributed by Dr Henry Knipe


Left weakness and dysphasia for 3.5 hours.

Patient Data

Age: 42
Gender: Male
Modality: CT

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.

Modality: MRI

Restricted diffusion confined to the right anterior cerebral artery territory is present consistent with infarction.

Case Discussion

ACA territory infarcts are much less common then MCA territory infarcts. Cardio-embolic events are the most common cause.
