Post-stroke Epilepsy Presenting as Focal Paroxysmal Pain / 대한간질학회지

ABSTRACT

Post-stroke epilepsy presenting as paroxysmal pain is rare. In most cases, the characteristic pain nature responsible for this kind of post-stroke epilepsy is associated with lesion of somatosensory areas. In this case, however, the precental motor cortex was responsible lesion site. A 60-year-old male with right frontal cortical and subcortical infarction complained paroxysmal shock like painful sensation on left lower extremity. This sensory symptom began after 2 weeks of stroke, and all analgesics failed to relieve the pain. EEG revealed sharp and slow wave at right frontotemporal region. Antiepileptic drug medication dramatically reduced the pain. In addition, epileptiform discharge disappeared after antiepileptic medication. In this paper, we report a post-stroke epilepsy presenting as focal paroxysmal pain associated with involvement of precental motor cortices.
