Refractory temporal seizures with crossed cerebellar diaschisis assessment with arterial spin-labeling

Crossed cerebellar diaschisis in patients with epilepsy are uncommon. This case reports a patient with refractory partial seizures who developed hemicerebellar involvement contralateral to an insular epileptogenic focus. The diaschisis was assessed with arterial spin-labeling, a recently developed non-invasive magnetic resonance perfusion sequence.
