title: Crossed cerebellar hyperperfusion in symptomatic epilepsy--two case reports.
abstract: A 74-year-old female with cerebral infarction and a 78-year-old female with cerebral glioblastoma suffered complex partial seizure. Ictal perfusion single photon emission computed tomography in these patients showed the interesting phenomenon of 'crossed cerebellar hyperperfusion,' a reversed crossed cerebellar diaschisis. The mechanism is probably spread of electrical seizure through efferent projections, and may be related to the cerebellar atrophy seen in patients with long-standing partial epilepsy.
