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.

Artemisia annua is a wormwood. Because it may induce Cytochrome P450 2C19 enzyme, Artemisia annua may have an influence on antiepileptic drugs which are substrates for the enzyme. This influence may negatively affect seizure control of epilepsy patient. We present a patient whose seizures were induced by Artemisia annua, despite he was taking levetiracetam which is not a substrate for the hepatic enzyme. Therefore there would be another mechanism of seizure induction of Artemisia annua besides hepatic metabolism.
