      SPECT and DWI Studies Suggest They are Ictal.

AB  - Lateralized periodic discharges (LPDs) are unilateral electroencephalography 
      (EEG) waveforms, recurring at regular intervals. There has been a long-lasting 
      debate about whether they represent ictal or interictal phenomena. Very few 
      patients in the literature have been investigated with multimodal functional 
      imaging techniques. Here, we present a 58-year-old male patient with symptomatic 
      epilepsy who had cerebral venous sinus thrombosis in the right temporo-parietal 
      area and dural arteriovenous fistula (dAVF) over the left fronto-parietal region. 
      He developed acute speech disturbances and altered mental status after a 
      generalized tonic-clonic seizure. Video-EEG monitoring (VEEGM) demonstrated LPDs 
      over the left fronto-central area, overlapping in part with the dAVF. 
      Diffusion-weighted imaging (DWI) and apparent diffusion coefficient (ADC) 
      sequences revealed restricted diffusion compatible with cytotoxic edema, whereas 
      single-photon emission computed tomography (SPECT) indicated hyperperfusion in 
      the same region, leading to the conclusion that he was having possible 
      nonconvulsive status epilepticus (NCSE). An increase in antiseizure medications 
      led to gradual improvement in clinical status and the disappearance of LPDs.
