Vascular Hyperemia and Crossed Cerebellar Diaschisis in MELAS Patient Presented as Stroke-Like Episode and Seizure

Mitochondrial encephalopathy, lactic acidosis, and stroke-like episodes (MELAS) is one of the mitochondrial disorders that can present as a stroke-like episode or seizure. Although the pathophysiology of MELAS remains inconclusive, the main possibilities are thus far thought to be mitochondrial cytopathy and angiopathy. This case report describes a 61-year-old woman diagnosed with MELAS who presented simultaneously with vascular hyperemia and crossed cerebellar diaschisis. J Korean Neurol Assoc 31(3):183-185, 2013
