Computed tomography (CT) of the head. CT head showed a right temporal contusion with mixed density and surrounding vasogenic edema (dashed circle; (a)). She also had a small right frontal subdural hemorrhage (arrows; (b)).

Computed tomography (CT) head showed a right temporal contusion with surrounding vasogenic edema and a small right frontal subdural hemorrhage (Figure 1).
Continuous electroencephalography (CEEG). CEEG shows generalized slowing with triphasic waves. The three phases of the wave that give the classic triphasic morphology are highlighted. Intracranial pressure at the time of this CEEG was 6 mmHg.

CEEG on propofol now showed diffuse slowing and generalized periodic discharges with TW (Figure 2). Once her intracranial hypertension was reduced with osmotic therapy and sedation, TW reappeared to the pattern shown in Figure 2.
Continuous electroencephalography (CEEG). CEEG shows generalized slowing with attenuation of triphasic waves. Intracranial pressure at the time of this CEEG was 50 mmHg.

During these episodes, CEEG showed attenuation of TW (Figure 3).
