Infarction of the occipital pole causes homonymous hemianopia, and release hallucinations occasionally occur in the region of the field defect.1,2 A 64-year-old woman developed acute right homonymous hemianopia with vivid hallucinations in the right visual field. She drew what she experienced, including colored pinwheels and lines at right angles (figure, A). Because light exacerbated the

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). A direct communication was present between the right ICA 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 occipital lobe is concerned with visual processing and is composed of three Brodmann areas: primary visual cortex (Brodmann area 17) secondary visual (association) cortex (Brodmann areas 18 and 19) Sulci and gyri.
An occipital lobe stroke is a stroke affecting the occipital lobe, which is the area in the back of the brain that plays a key role in vision and allowing us to recognize what we see. As such, occipital lobe strokes are primarily associated with changes in vision. 1

Differentiating hemorrhagic infarct from parenchymal intracerebral hemorrhage can be difficult. The immediate and long-term management of the two conditions are different and hence the importance of accurate diagnosis. Using a series of intracerebral hemorrhage cases presented to our stroke unit, we aim to highlight the clues that may be helpful in distinguishing the two entities.
3,8 Imaging usually facilitates diagnosis, as stroke has typical imaging features at different stages and follows typical topographic patterns. Wedge shaped loss of grey-white matter differentiation within the left medial occipital lobe is in keeping with an acute left PCA infarct. No intracranial hemorrhage. No significant mass effect. Periventricular white matter hypoattenuation is most likely in keeping with moderate chronic small vessel ischemia. Ventricular size is normal.

Occipital lobe epilepsies (OLEs) manifest with occipital seizures from an epileptic focus within the occipital lobes. Ictal clinical symptoms are mainly visual and oculomotor. Elementary visual hallucinations are common and characteristic. Postictal headache occurs in more than half of patients (epilepsy–migraine sequence).

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. The occipital lobe covers 12% of the neocortex, which is involved in cognition, reasoning, motor skills, and sensory perception (6). The right and left occipital lobes are separated by a cerebral fissure (7).

The authors determined the origin, course, and region of supply of each occipital branch: the parieto-occipital, calcarine, posterior temporal, and common temporal arteries, as well as the lingual gyrus artery. "adopted daughter 7 had an mri showed old infarcts to left occipital/ left temporal lobes. she was recently dx mosaic turners syndrome. possible cause?" Answered by Dr. Milton Alvis, jr: Infarcts (DeadCells): are a result of either loss of blood supply or t Se hela listan på appliedradiology.com 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. For example, in a patient with a fetal variant or even a patent PCoA with anteroposterior flow, a severe carotid stenosis could be responsible, and carotid endarterectomy might be warranted to prevent further ischemic strokes.
