A. Preoperative CT Scan brain showing right-sided temporoparietal acute subdural hematoma and a right frontal hematoma with a significant midline shift to the left. B. Postoperative magnetic resonance imaging (MRI) brain showing focal gliotic area with long TR weighted hyperintensity in the right frontoparietal region, related to post the traumatic sequel. C. Postoperative MRI brain showing asymmetry of hippocampus without any signal changes.

CT brain had revealed a right temporoparietal acute subdural hematoma and a right frontal hematoma with a significant midline shift to the left requiring right sided decompressive hemicraniectomy [Fig. 1A]. Imaging with MRI brain showed gliotic areas in the right frontal and parietal lobes which denoted the sequel of previous trauma [Fig. 1B and C].
A. Preoperative Electroencephalography (EEG) showing lateralized periodic discharges (LPDs) (arrows). B. Postoperative EEG showing no discharges under the breach rhythm in the right hemisphere. Filter settings were high pass at 1.59 Hz and low pass at 70 Hz, and sensitivity at 7 mu volts/mm.

S.p.A., BE Light, Firenze, Italy). Scalp recordings using 10-20 system of electrode placement showed theta range background with right breach rhythm and lateralized periodic discharges (LPDs), [Fig. 2A]. Postoperative EEG showed the similar background with a breach rhythm from the right hemisphere [Fig. 2B].
