Intracranial Arteries Overview

(Top) Typical vascular territories of the 3 major cerebral arteries are depicted. The most common distribution of the anterior cerebral

artery (ACA) is shown in green, as seen from lateral (upper left), medial (upper right), from top down (lower left) and from the

submentovertex perspective (lower right). The ACA supplies most of the medial hemispheric surface except for the occipital lobe.

(Middle) Usual vascular territory of the MCA is shown in red. MCA typically supplies most of the lateral and superior surface of the

hemisphere except for a small strip over the vertex (ACA), occipital pole, and inferolateral temporal lobe (PCA). (Bottom) Usual vascular

territory of the PCA is depicted in purple. The PCA supplies the occipital poles and most of the undersurface of the temporal lobe except

for its tip, which is usually supplied by the MCA.
