Acute 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 کاملCorticospinal 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 کاملDiffusion-weighted imaging of acute corticospinal tract injury preceding Wallerian degeneration in the maturing human brain.
BACKGROUND AND PURPOSE Wallerian degeneration, the secondary degeneration of axons from cortical and subcortical injury, is associated with poor neurologic outcome. Since diffusion-weighted (DW) imaging is sensitive to early changes of cytotoxic edema, DW imaging may depict the acute injury to descending white matter tracts that precedes Wallerian degeneration; this injury is not visible on con...
متن کاملNatural History and Prognostic Value of Corticospinal Tract Wallerian Degeneration in Intracerebral Hemorrhage
BACKGROUND The purpose of this study was to define the incidence, imaging characteristics, natural history, and prognostic implication of corticospinal tract Wallerian degeneration (CST-WD) in spontaneous intracerebral hemorrhage (ICH) using serial MR imaging. METHODS AND RESULTS Consecutive ICH patients with supratentorial ICH prospectively underwent serial MRIs at 2, 7, 14, and 21 days. MRI...
متن کاملWallerian degeneration of the corticospinal tract in a middle cerebral artery infarction.
An 18-year-old white woman with a history of end stage renal failure secondary to hemolytic uremic syndrome, bilateral nephrectomies, rejection of two kidney transplants, and currently on chronic ambulatory peritoneal dialysis was admitted to the hospital with abdominal pain likely secondary to peritonitis. She coded while in the hospital and resuscitation efforts were unsuccessful. She had a h...
