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...

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 is a neurological deficit characterized by partial loss of muscle strength in one half the body. It has been reported that skin on hemiparetic side may differ from normal body region for some reasons, therefore diseases progress differently, and be seen more frequently or less frequently. However, there no information literature regarding course tinea versicolor lesions these patien...

We describe a 73-year-old man with ataxic hemiparesis following infarction of the ventrolateral nucleus of the thalamus demonstrated by computed tomography and magnetic resonance imaging. Cerebellar ataxia was most likely due to interruption of the dentatorubrothalamocortical fibers at the level of the injured ventrolateral nucleus. Hemiparesis was probably caused by local edema compressing the...

A 73-year-old male presented with a glioblastoma that was detected at the initial stage in the developmental process. He suffered cerebral infarction. Follow-up magnetic resonance (MR) imaging showed no abnormality. Ten months later, he had transient right hemiparesis. Diffusion-weighted and fluid-attenuated inversion recovery (FLAIR) MR imaging showed a hyperintense area in the left frontal lo...

Lacunar stroke was diagnosed in 337 (26%) of the 1,273 patients with cerebral infarction among the 1,805 total in the Stroke Data Bank. We analyzed the 316 patients with classic lacunar syndromes. Among these, 181 (57%) had pure motor hemiparesis, 63 (20%) sensorimotor syndrome, 33 (10%) ataxic hemiparesis, 21 (7%) pure sensory syndrome, and 18 (6%) dysarthria-clumsy hand syndrome. No striking ...

BACKGROUND AND PURPOSE Children with congenital hemiparesis have greater asymmetry in diffusion parameters of the pyramidal tracts compared with control subjects. We hypothesized that the asymmetry correlates with the severity of hemiparesis and that diffusion metrics would be abnormal in the affected tracts and normal in the unaffected tracts. MATERIALS AND METHODS Fifteen patients with cong...
