We report the case of a 56-year-old woman who developed status epilepticus (SE) related to independent occipital foci as clinical manifestation of posterior reversible encephalopathy syndrome (PRES) in the background of Guillain-Barrè syndrome (GBS). SE resulted from a series of focal seizures clinically characterized by left- and rightward deviations of the head and consequent oculoclonic move...

BACKGROUND Nonketotic hyperglycemia often causes seizures. Recently, seizures associated with nonketotic hyperglycemia have been found to be associated with subcortical T2 hypointensity on magnetic resonance imaging, especially in the occipital lobes. However, the mechanism remains unclear, although iron accumulation is suggested. We present a case of occipital lobe seizures associated with non...

Occipital lobe infarcts, hemorrhages, or metastatic tumors can present with complex visual hallucinations, sensory or proprioceptive abnormalities, speech dysfunction, visual loss, and homonymous hemianopia (HH). Treatment of occipital lobe seizures is by single or multiple antiepileptic drugs. We present a case of idiopathic occipital lobe epilepsy where the seizures were controlled by antiepi...

A 60-year-old woman had sudden onset transient visual symptoms in her right visual field after having worsening postural headaches for 1 year. Visual symptoms included palinopsia or abnormally recurring visual imagery, macropsia, unformed hallucinations, and hemianopia (figure 1). The symptoms lasted from 5 minutes to a few hours. Imaging demonstrated multiple cavernous hemangiomas including on...

Dysembryoplastic neuroepithelial tumor (DNET) is a benign brain tumor which commonly presents as childhood-onset temporal lobe epilepsy (TLE). We present a case of histologically proven DNET with a clinical presentation and scalp EEG suggestive of adult-onset TLE. MRI showed an occipital lesion. PET showed abnormal metabolism of the occipital lesion and the ipsilateral temporal lobe; raising co...

Mirror focus is one of the evidence of progression in epilepsy, and also has practical points for curative resective epilepsy surgery. The mirror foci are related to the kindling phenomena that occur through interhemispheric callosal or commissural connections. A mirror focus means the secondary epileptogenic foci develop in the contralateral hemispheric homotopic area. Thus mirror foci are mos...

In a previous report of 900 patients with epileptic seizures, 24 children had ictal vomiting. Twelve had a previously unrecognised syndrome of early onset benign childhood occipital seizures (EBOS) and three had symptomatic epilepsy. The other nine children with extraoccipital EEG foci or normal EEG are described in this paper based on a prospective follow up for a median of 9 years after their...
