Corticospinal tract pre-wallerian degeneration: a novel outcome predictor for pediatric stroke on acute MRI.
BACKGROUND AND PURPOSE In neonatal arterial ischemic stroke, pre-Wallerian degeneration in descending corticospinal tracts (DCST) on diffusion MRI (DWI) predicts poor outcome. This signal has not been studied in older children. METHODS A consecutive arterial ischemic stroke cohort (1 month to 18 years) with acute DWI and >12 months of follow-up were enrolled (SickKids Children's Stroke Progra...
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 کاملTeaching NeuroImages: Multicompartmental intracranial hemorrhage in a pediatric patient.
A previously healthy 9-year-old girl presented with sudden-onset headache followed by confusion. In the emergency department, she was hypertensive, bradycardic, and no longer responsive to any stimuli. An emergent head CT scan demonstrated a left frontal intraparenchymal hematoma with intraventricular and subarachnoid extension as well as subfalcine herniation (figure). She underwent decompress...
متن کاملTeaching NeuroImages: Gasperini syndrome.
Gasperini syndrome is a rare crossed brainstem syndrome characterized by ipsilateral impairment of the VI, VII, and occasionally VIII cranial nerves and contralateral sensory loss. The syndrome, initially described by Ubaldo Gasperini in 1912, results from a lesion of the caudal pons tegmentum (figure e-1, links.lww.com/WNL/A47). The most frequent cause is the occlusion of the long circumferent...
