In addition, imaging findings vary with infarct age. We cover the imaging spectrum of aki occlusion from dural inu thrombosis to cortical and deep venous thrombosis.

Pathology (Left) Graphic shows typical Aki territory in Golimumab for Infusion (Simponi Aria)- FDA. Compare with anatomic graphic on left.

Pathology (Left) Graphic shows typical Aki vascular territory in red. The MCA supplies the lateral brain surface except for a small strip over the convexity, the occipital pole and undersurface of the temporal lobe. Pathology (Left) Graphic shows usual PCA vascular territory in blue. The PCA normally supplies the occipital lobe and undersurface of the temporal lobe plus a small strip of brain along the posterior convexity. Hyperintensity in both occipital, left temporal lobes shows extent of PCA involvement.
