This is a coronal section of the brain showing bilateral anterior cerebral artery infarcts. The infarcts involve structures supplied by the anterior cerebral artery such as the superior frontal gyrus, the cingulate gyrus, and the corpus callosum. Patients with this type of infarct will show bilateral lower extremity weakness or paralysis associated with upper motor neuron signs in the affected extremities. The upper extremities and the face will be spared in this type of lesion because their cortical areas are supplied by the middle cerebral artery.
