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 .

The tubular hyperdensity next to the hematoma was a thrombosed inferior anastomotic vein (vein of Labbé). The subsequent MRI performed 12 hours later (Figure 7) performed for the possibility of an underlying mass reveals progression with infarction of the right temporal and occipital lobe superimposed on the temporal lobe hemorrhage.

Fig. 18.1 Acute infarct. Diffusion-weighted images showing acute lacunar infarct (arrow) in posterior limb of right internal capsule Less common etiologies, representing less than 5 % of acute stroke, include vasculopathies, immune-related diseases, hypercoagulable states, arterial dissection, global hypoperfusion, venous infarction, and mitochondrial disorders.
Se hela listan på appliedradiology.com Seven patients, each with a different pattern of homonymous visual loss caused by ischemic infarction of the occipital lobe, were studied with computed tomography. The retinotopic representation of the visual field on the occipital lobes, as determined by these studies, fully confirms those deduced by previous investigators. 2011-12-22 · any infarct in the brain is normally irrepairable .. or vision loss with occipital ( Brain) Infarct .

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 ).
CT study of brain shows an infarct involving left occipital lobe. Area of involvement corresponds to left PCA territory. PCA territory infarct is most often caused by a cardiac embolus or an embolus from an occluded or stenotic proximal vertebral or basilar artery.

If you’re having an occipital If a patient has an occipital lobe infarct, a possible relationship between the infarct and the parent artery of the PCA needs to be considered.
Results: On MRI, a left occipital lesion with mild enhancement after gadolinium infusion on the T1-weighted image, bright signal with some mass effect on the T2-weighted image, and the diffusion-weighted imaging suggested a diagnosis of an acute infarct. magnetic resonance imaging (MRI) of the brain, which revealed evolving late subacute infarcts involving the bilateral parieto-occipital cortices and no acute intracranial hemorrhages (Figure 1A) 2016-06-20 2018-11-01 2021-01-25 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.
