Crossed cerebellar diaschisis: a radiological finding in status epilepticus not to miss

In the setting of status epilepticus, the excessive excitatory input from supratentorial epileptiform focus leads to the functional deactivation of the contralateral cerebellar hemisphere through the corticopontocerebellar pathway. 2 MRI of the brain with DWI is a useful investigation to identify CCD in status epilepticus at an early stage. 3 Learning points Crossed cerebellar diaschisis (CCD) refers to a depressed functional activity of the cerebellar hemisphere contra lateral to the supratentorial lesion.
