EEG findings during the ictal phase. Shows periodic spike-wave complexes at 1.5-2 Hz and 100-150 uV of amplitude with phase opposition on T3 mixed with poly-spikes, described as Lateralized Periodic Discharges plus superimposed fast activity (LPDs + F) on the left fronto-temporal derivations.

A 21 derivations EEG recording was then performed which showed mid-temporal continuous spike-wave complexes at 1.5-2 Hz and 100-150 uV of amplitude with phase opposition on T3 with superimposed fast activity (Lateralized Periodic Discharges plus superimposed fast activity, LPDs + F pattern), (Fig. 1).
Magnetic Resonance Imaging (MRI) of the brain performed after SE recovery. In (A) Axial Fluid Attenuated Inversion Recovery (FLAIR) sequence and in (B) T2-weightened sequences showing a large neoplastic lesion involving the left temporo-insular area.
