Computed tomography (CT) scans showing an example of rapid worsening. A : Initial head CT reveals a mixed density, thick ASDH with cerebral contusion, traumatic SAH, and moderate midline shifting. B : Three hours later, head CT shows slight hematoma thinning and a midline shifting improvement. C : However, 3 days later, the patient showed a sudden neurologic deterioration (GCS score 8), and follow-up head CT reveals aggravated hematoma and midline shifting. Craniectomy was performed immediately. Her final GCS score was 10. ASDH : acute subdural hematoma, SAH : subarachnoid hemorrhage, GCS : Glasgow Coma Scale.
