Cerebellar hemorrhage vs Pontine hemorrhage

[docverpamil]

Uworld says,with cerebellar hemorrhage there is facial weakness and gaze palsy.
And with pontine hemorrhage there is coma and paraplegia.
Can anyone explain the reason behind these findings!

There isn't usually facial weakness and gaze palsy with cerebellar haemorrhage. However, if the bleed extends, there can be pressure effects on the pons causing compression of CN VI (gaze palsy) and VII (facial weakness).

In any brainstem hemorrhage, the various tracts are at risk, hence you can see paraplegia if the corticospinal tract is affected and coma if the reticular formation is affected.
