Cerebral Vascular Territories

The cerebral hemispheres are supplied with blood via three major arteries: the anterior, middle, and posterior cerebral arteries.  This coronal section through the frontal lobes shows hemorrhage involving the vascular territory of which of these three major cerebral arteries?

Cerebral Vascular Territories

Answer: 

The cerebral hemispheres are supplied with blood via three major arteries: the anterior, middle, and posterior cerebral arteries.  The infarction (or stroke), seen in a coronal section through the frontal lobes of this brain, is involving the vascular territory of the middle cerebral artery, which predominantly supplies the lateral aspects of the brain whereas the medial cerebral structures are supplied by the anterior and posterior cerebral arteries.
