pontocerebellar fibers

pontocerebellar fibers

[TA]
fibers arising from the nuclei of the basilar pons and primarily crossing the midline (there is a modest uncrossed projection), entering the cerebellum through the middle cerebellar peduncle and terminating as mossy fibers in the cerebellar cortex.

Finally, the pontocerebellar fibers terminate in the cerebellar hemispheres, vermis, and paraflocculus.
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.
The characteristic T2 hyper intense sign in pons and middle cerebellar peduncle ("Cross sign") reflects pontocerebellar fibers degeneration and despite very suggestive of MSA it can be found in other forms of parkinsonism.
sup][29] The radiological features could be found out when the atrophy and gliosis occurred in the transverse part of the pontocerebellar fibers traveling to the middle cerebellar peduncles, the crossing part of the pontocerebellar fibers at the pontine base, and the middle part of the reticular formation.
