Extent of pontine pyramidal tract Wallerian degeneration and outcome after supratentorial hemorrhagic stroke.
BACKGROUND AND PURPOSE Pyramidal tract Wallerian degeneration has been detected on magnetic resonance imaging (MRI) as T2-weighted high-intensity areas. We analyzed the relation between the extent of brain stem Wallerian degeneration and activities of daily living (ADL) after supratentorial hemorrhagic stroke. METHODS Twenty-six patients with supratentorial hemorrhage were examined on the cor...
متن کاملAcute corticospinal tract Wallerian degeneration is associated with stroke outcome.
BACKGROUND AND PURPOSE In children with stroke, poor motor outcome is associated with early Wallerian degeneration of the corticospinal tract that is seen on diffusion-weighted MRI. In this study we test the hypothesis that early diffusion changes also occur in the corticospinal tract (CST) of adults after stroke and that these lesions are associated with poor outcome. METHODS In this retrosp...
متن کامل[Wallerian degeneration after stroke: a new prognostic factor?].
Wallerian degeneration (WD) after ischemic stroke has been associated to persistent motor impairment, but signal intensity changes on conventional magnetic resonance imaging (MRI) are generally not detected until four weeks after the event. We report a 54 year old male patient, referred to our hospital for sudden-onset left hemiparesis. Cerebral CT showed right fronto-parietal infarct (middle c...
متن کاملWallerian degeneration of the pyramidal tract in capsular infarction studied by magnetic resonance imaging.
Using magnetic resonance imaging, we studied 24 patients with ischemic infarction of the internal capsule. Magnetic resonance imaging detected wallerian degeneration of the pyramidal tract below the capsular lesion in 11 patients (45.8%); all 11 had clinical evidence of pyramidal tract damage. In six additional patients magnetic resonance imaging findings, present only on axial slices, were con...
متن کاملHyperintense signal in pyramidal tract neurons in postoperative brain tumor: wallerian degeneration or neoplastic dissemination?
A 46-year-old man presented with behavioral changes and partial seizures over 20 days. Neurological examination showed mental confusion. Brain MRI showed a ringshaped lesion in the left frontal lobe (A and B). Surgery was performed (C) and pathology confirmed glioblastoma multiforme. The patient underwent radiotherapy and che motherapy. A control MRI (eight months later) showed hyperintense sig...
