(A) Computed tomography (CT) from the day of the accident showing acute right side hematoma with midline shift. (B) CT from 5 months after the event after cranium reimplantation showing an epidural hematoma, which required a second surgery. (C) Event-related potentials from an oddball paradigm at electrode Cz. Identifiable are congruent but slightly delayed N100 responses for frequent and novel tones with a peak latency of 128 msec. A discernible but delayed P300 with a peak latency at 457 msec is displayed for novels, indicating the detection and intensified processing of new and unexpected events. (D) Event-related potentials from a N400 paradigm at electrode C4. Identifiable N100, more pronounced for semantically correct sentence endings and smaller for incorrect sentence endings. Between 400 and 800 msec, a clearly visible but delayed N400 is displayed, indicating the detection and intensified processing of semantic violations.

After the operation, various complications occurred, including an epidural hematoma, which required a new surgery (see CT in Fig. 1B). EEG now showed an almost normal alpha rhythm. Event-related potentials (ERPs) for tone discrimination (P300) and semantic speech processing (N400) were clearly identifiable, albeit latency delayed (see Fig. 1C and D).
