A non-contrast CT scan demonstrates a right parieto-occipital scalp hematoma.
A thin right parieto-occipital subdural collection isodense to the cortex. Given that the patient fell and hit her head 45 minutes ago, this suggests that this could be a hyperacute subdural hematoma.
The scan was otherwise unremarkable.
A follow-up CT scan was recommended after 12 hours.
