Occipital Hemianopia Secondary to Stroke (CT scan) | |
A subsequent CT scan of the brain revealed a well defined, wedge-shaped, hypodense lesion in the right occipital lobe (arrow). Note that the occipital pole is uninvolved, which accounts for the perimetric finding of macular sparing. Presumably, the patient experienced vaso-occlusive event involving the right posterior cerebral artery. The dual blood supply of the occipital pole may have served to limit the area of infarction to the more anteriorly situated cortex. | |
