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. When evaluating the occipital condyles, it is important to remember that multiple variations may be present, such as

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. CT brain images - appearances of an occipital infarct as seen on CT of the brain. A well-defined area of low attenuation is seen in the left occipital lobe.

The main clue to the presence of hemorrhagic infarct on computed tomography scan is the topographic distribution of the stroke. Additional imaging modalities such as computed tomography angiogram, perfusion, and magnetic resonance imaging may provide additional information in differentiating hemorrhagic infarct from primary hemorrhages.

14 Aug 2017 Look for associated features like: – hydrocephalus, giant aneurysm, infarction and hematoma. CLINICAL HISTORY!!! ** Gold standard to detect 

RULING OUT ACUTE MYOCARDIAL INFARCTION. AMI is defined as Imaging evidence of new loss of viable myocardium or new regional wall motion abn.

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.

7-9 The etiologies of infarctions in the occipital lobe are primarily emboli from the heart or vertebrobasilar artery system. 7 The main clue to the presence of hemorrhagic infarct on computed tomography scan is the topographic distribution of the stroke. Additional imaging modalities such as computed tomography angiogram, perfusion, and magnetic resonance imaging may provide additional information in differentiating hemorrhagic infarct from primary hemorrhages.

An occipital stroke is a stroke that occurs in your occipital lobe. If you’re having an occipital Two Cases of Occipital Infarction Following Cardiac Catheterization Armando Oliva, CPT, MC, USAR, and Barbara Scherokman, MD Transient visual disturbance following cardiac catheterization has been regarded as a benign and transient complication.

Additional imaging modalities such as computed tomography angiogram, perfusion, and magnetic resonance imaging may provide additional information in differentiating hemorrhagic infarct from primary hemorrhages.

The right-sided occipital abnormality was interpreted as a false penumbra produced by reperfusion of an incomplete chronic infarct, and the left-sided abnormality was interpreted as a true penumbra. Follow-up unenhanced CT performed 1 year later showed the expected interval development of encephalomalacia in the left occipital region ( Fig 3f ). 10.1055/b-0034-102661 Infarction In young patients, the etiologies for cerebral infarction are many and varied, in distinction to adults.

We describe a classic case of selective apperceptive prosopagnosia due to an ischemic infarct of the left occipital lobe with extension to the lingual gyrus. It is well-established that acquired prosopagnosia usually involves the right more than the left occipital cortex, with localization of lesions bilaterally more than unilaterally.

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.
