1. Cortical Superficial infarct of the frontal, tempo-ral, parietal, or occipital lobe(s) that may extend into the underlying white matter but does not extend into the white matter at the level of the basal ganglia. The infarct is in the vascular territory of a large cerebral artery (e.g., carotid artery, middle cerebral artery, posterior Small cerebellar infarcts are often only detected as an incidental (cerebellar cortical) infarct cavity, which are most often smaller than 1 cm and typically involve the cerebellar cortex 10,11. They are easily observed on MRI (and CT) due to high intrinsic contrast between CSF within the cavity and the adjacent parenchyma. An infarct of the parietal lobe is the death of its tissues caused when an obstruction of the blood supply causes a lack of oxygen. The parietal lobe is one of the four major lobes of the brain. The left and right parietal lobes control the sensations of touch, pressure, pain, spatial awareness, and judgment of texture, weight, size, and shape.

The two most striking consequences of PPC damage are apraxia and hemispatial neglect. 2014-07-01 Bilateral cortical blindness and Anton syndrome, are most commonly caused by ischaemic stroke. In this condition, patients have loss of vision but deny their blindness despite objective evidence of visual loss. We report a case of a patient with multiple cardiovascular risk factors who developed recurrent bilateral occipital lobe infarct with Anton syndrome.
