MCA with accompanying ACA infarcts

At presentation (upper two images), on the unenhanced CT only a small chronic white matter infarct is noted in the left frontal lobe. CTA (thick MIP) reveals a paucity of vessels in the left ACA and MCA distributions. The CT one day later (lower two images) reveals abnormal low density in both the ACA and MCA distributions on the left, with slightly improved demarcation on the post-contrast scan.
