Seizure semiology reflects spread from frontal to temporal lobe: evolution of hyperkinetic to automotor seizures as documented by invasive EEG video recordings.

This patient report demonstrates the importance of seizure evolution in the localising value of seizure semiology. Spread of epileptic activity from frontal to temporal lobe, as demonstrated by invasive recordings, was reflected by change from hyperkinetic movements to arrest of activity with mild oral and manual automatisms.

Ictal/interictal EEG patterns and functional neuroimaging findings in subcortical band heterotopia: report of three cases and review of the literature.

Subcortical band heterotopia (SBH) is a rare, genetic disorder of neuronal migration, which is seen almost exclusively in females. Little is known about the functionality of the band heterotopia, in terms of both physiology and pathology, in this malformation. Patients are reported to have several different types of seizures, which are usually drug resistant. Interictal EEG findings are known to correlate with the type of seizures, however less is known about the ictal EEG patterns. We present 3 female patients who were investigated at our center with video-scalp EEG monitoring, interictal single photon emission computed tomography (SPECT), functional magnetic resonance (MR) imaging (fMRI) and MR spectroscopy (MRS) besides routine MR imaging. They had several different types of seizures, and one of them reported also having circling seizures that have not been reported previously in patients with SBH. Ictal EEG recordings were remarkable for their unusual patterns of propagation. The findings in structural and functional neuroradiological investigations are discussed in light of the literature.
