2014-05-19 · #### Summary points About 20-25% (range 17-40%) of the 150 000 ischaemic strokes in the United Kingdom each year affect posterior circulation brain structures (including the brainstem, cerebellum, midbrain, thalamuses, and areas of temporal and occipital cortex), which are supplied by the vertebrobasilar arterial system.1 Early recognition of posterior circulation stroke or transient ischaemic

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. A suspicion of this condition infarct A volume of dead tissue lying within living tissue, the death being caused by local loss of blood supply. Infarcted tissue swells and becomes firm, and blood vessels around an infarct widen. Plasma and blood may pass into the infarct, increasing the swelling.

The occipital lobe is the seat of most of the brain's visual cortex, allowing you not only to see and process stimuli from the external world, but also to assign meaning to and remember visual perceptions.

Occipital strokes occur when you have an obstruction or hemorrhage in the posterior cerebral artery, which is located in the brain. CT brain images - example of evolution of CT appearances in acute v chronic infarct. Acutely the CT may be normal or show subtle signs such as the 'loss of insular ribbon' sign, or the 'dense MCA' sign. A longstanding infarct appears as an area of low density of grey and white matter in a vascular territory of the brain.

Discussion Cortical blindness has been associated with bilateral lesions of the primary visual cortex of the occipital lobes secondary to hypoxia, cardiac arrest, vasospasm, cardiac embolism [3], head Occipitalloben, nackloben eller lobus occipitalis är den del av hjärnan som är hem för synbarken och är därav den del av hjärnan som främst hanterar visuella intryck och processer genom att hjälpa till att bearbeta information från ögat så att vi kan förstå vad vi ser. Den är belägen i storhjärnsbarkens allra bakersta del.

Since most patients in previous reports were not studied with CT, it is impossible to say how often these patients will have residual occipital infarctions. Our two cases suggest that transient visual disturbance following cardiac The Occipital Lobe: The occipital lobe is the lobe of the brain located at the very back of the head. It functions mostly to receive and interpret visual information that is taken in by the eyes.
