To clarify the clinical features and mechanism of infarction in the posterior cerebral artery territory, we investigated 35 consecutive patients who presented with homonymous visual field defects and occipital infarction documented by computed tomography. Cerebral angiographic findings in 23 patients, and the clinical features of rare transient

The parietal lobe, temporal lobe, and occipital lobes are medially separated by a deep groove called the parieto-occipital sulcus (8). 2016-09-12 Abnormalities extended from the precentral gyrus down to the centrum semiovale and corona radiata. At the level of the temporal and occipital horns, the posterior cerebral white matter in all patients was involved more than the anterior (Fig 2, G–I). 2011-12-22 10.1055/b-0034-102661 Infarction In young patients, the etiologies for cerebral infarction are many and varied, in distinction to adults. Leading causes include congenital and acquired heart disease, together with sickle cell disease. In the elderly, infarcts are most often due to atherosclerosis, with vessel occlusion due to either thrombosis or embolism ( Fig. 1.55 ).
Ventricular size is normal. 2018-11-01 Clinical presentation. Symptoms of posterior cerebral artery stroke include contralateral homonymous hemianopia (due to occipital infarction), hemisensory loss (due to thalamic infarction) and hemi-body pain (usually burning in nature and due to thalamic infarction) 3 . If bilateral, often there is reduced visual-motor coordination 3 . occipital infarct (Figure 1) in the PCA territory and a right frontal infarct. Cerebral angiography revealed a subtotal occlusion of the right ICA, with minimal antegrade blood flow and patent cervical and intra-cranial ICA on later films (Figure 2).
Risk factors for ischemic stroke largely mirror the risk factors for atherosclerosis and include age, gender, family history, smoking, hypertension, hypercholesterolemia, and diabetes mellitus. An occipital stroke affects the part of your brain that controls your ability to see things. It may cause temporary or permanent visual disturbances.

These structures are approximated at two major joints, the atlanto-occipital and atlantoaxial joints. The main clue to the presence of hemorrhagic infarct on computed tomography scan is the topographic distribution of the stroke.

Imaging of watershed infarction should also aim to determine the presence and severity of arterial stenosis and occlusion. Cortical (external) border zones infarct.

Watershed infarct: T1 MRI of an ischemic stroke in the brain without (left) and with (right) contrast. Specialty: Neurology: A watershed stroke is defined as a brain ischemia that is localized to the vulnerable border zones between the tissues supplied by the anterior, posterior and middle cerebral arteries.
We describe two cases of computed-tomography-documented occipital occipital bone. These articulate with the supe-rior articular surfaces of the lateral masses of the atlas. The anterior aspects of the occipital con-dyles contain foramina that allow the hypoglos-sal nerve to enter the skull.

structural occipital lobe damage can result, even in patients who appear to recover clinically. 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 …
In most cases, these patients deny their blindness and their behavior is as if they have an intact vision.
