Remote perfusion changes after pure brain stem infarction may be seen both infratentorially and supratentorially and depend on the lesion site rather than on the neurological deficit.In this context,our study confirmed damage to the corticopontocerebellar pathways as the key event in the genesis of a crossed cerebellar diaschisis.The exact mechanisms causing ipsilateral cerebral hemispheric diaschisis await further clarification. |
