1] It has been reported that WD may occur in the 1st week after stroke (at the earliest), and that corticospinal tracts are commonly involved.
Hot cross bun sign refers to the cruciform shaped pontine T2 hyperintensity in multiple system atrophy due to selective loss of myelinated transverse pontocerebellar fibers and neurons in the pontine raphe and sparing of the pontine tagmentum and corticospinal tracts.
6] Typical patterns of brain involvement in NMOSD, although not pathognomonic, include lesions of the dorsal medulla/area postrema, periependymal regions in the brainstem, diencephalic structures, or cerebral hemispheres or long lesions spanning much of the corpus callosum or corticospinal tracts, corresponding to regions of high AQP4 expression.

March 28, 2016 -- Researchers here have successfully directed stem cell-derived neurons to regenerate lost tissue in damaged corticospinal tracts of rats, resulting in functional benefit.
Morphology criterion: Impaired motor conduction of the corticospinal tracts by tracking changes in the pattern and duration of MEP waveform morphology.
Neuropathologic examination of FSP reveals axonal degeneration in the terminal portions of the spinal cord affecting corticospinal tracts and dorsal column fibers with little involvement of the spinocerebellar tracts.
His MRI Brain done on Day 3 of admission revealed the following interesting finding: Hyperintense signal change in pons with partial sparing of the tegmentum, ventrolateral pons and corticospinal tracts on FLAIR (Fig.
Brown-Sequard syndrome, first reported in 1849, is characterised by hemisection of the cord with disruption of the descending lateral corticospinal tracts resulting in ipsilateral hemiplegia, and damage of the ascending lateral spinothalamic tracts (which cross within one or two levels of the dorsal root entrance) resulting in contralateral loss of pain and temperature.
This is what the doctors said about Jason's condition: "Subacute combined degeneration of the spinal cord involving clearly the pyramidal tract as well as the corticospinal tracts based on MRI of the spine; Cyanocobalamin deficiency based on the very low level of his first B12 blood serum level; Nitrous oxide abuse; His hands are also getting weak in terms of his grip strength.
ALS is a progressive, degenerative neuromuscular condition of unknown etiology affecting the corticospinal tracts and the anterior horn of the spinal cord, leading to dysfunction of the upper and lower motor neurons.
We also traced descending corticospinal tracts with an axon tracer in these SCI animals and found a greater number of axons to grow into the scar tissues, although a small number of corticospinal axons were detected in the caudal spinal cord.
