Arterial Spin Labeling Perfusion MRI of Crossed Cerebellar Diaschisis in a Patient with Simple Partial Status Epilepticus

ABSTRACT

Crossed cerebellar diaschisis (CCD) is known to be due to a contralateral supratentorial lesion decreasing blood flow and the metabolism in a cerebellar hemisphere. Arterial spin labeling (ASL) is an imaging technique that utilizes arterial blood water as a tracer for quantifying the regional cerebral blood flow in magnetic resonance imaging (MRI). This case was a patient with simple partial status epilepticus (SPSE) and CCD confirmed by ASL-perfusion MRI. Controlling the SPSE resulted in improvement of CCD being observed in the follow-up ASL-perfusion MRI.
