چکیده

A 61-year-old woman developed right hemiparesis with homolateral cerebellar-type ataxia. Computed tomography and magnetic resonance imaging demonstrated left corona radiata lesions, not present on magnetic resonance imaging 1 year earlier. No brainstem lesions were identified, suggesting that ataxic hemiparesis can result from lesions in the corona radiata.

The anterior choroidal artery does not supply the corona radiata and lateral ventricular wall.

BACKGROUND AND PURPOSE We sought first to characterize the clinical syndromes of patients found to have angiographic, computed tomographic, or magnetic resonance imaging scan indexes of anterior choroidal artery territory infarction and then to determine the frequency of involvement of the periventricular corona radiata in such patients. METHODS Sixteen patients were selected based on angiogr...

Ipsilateral hemiparesis caused by a corona radiata infarct after a previous stroke on the opposite side.

Ipsilateral hemiparesis after a supratentorial stroke is rare. However, the role of the reorganization of the unaffected hemisphere in recovery after a stroke is poorly understood. Two patients developed ipsilateral hemiparesis after a left corona radiata infarct. Both of these patients had previously experienced contralateral hemiparesis after a right-sided supratentorial stroke. Functional ma...

Ataxic Hemiparesis Associated with Cortical Infarct Localized in the Postcentral Gyrus

Ataxic hemiparesis (AH) is a classic lacunar syndrome associated with localized damage to the pons, internal capsule, thalamus, or corona radiata. A depression of metabolic activity known as crossed cerebellar diaschisis (CCD) is frequently observed in the cerebellar hemisphere contralateral to the site of the lesion in patients with AH. Though small cortical or subcortical lesions may result i...

Anisotropy of water diffusion in corona radiata and cerebral peduncle in patients with hemiparesis.

Diffusion tensor imaging is a magnetic resonance method which provides quantitative measurements of the directionality (anisotropy) of diffusion. Anisotropy measurements can be used to obtain quantitative information about the microstructural integrity of white matter tracts. In intact tracts diffusion is restricted and directional because water molecules move predominantly longitudinally to tr...

Hemiparesis and lateralized cortical lesions associated to severe hypoglycemia.

Dr. Marcus Sabry Azar Batista – Rua Olavo Bilac 1737 64001-020 Teresina PI Brasil. E-mail: [email protected] Severe hypoglycemia may occur as a complication of insulin therapy or as a consequence of accidental or suicidal insulin injections. It may result in a variety of neurological symptoms such as focal deficits, epileptic crisis, coma state and death. There is a relative rarity of repo...
