Non-contrast CT scan of the brain showed:

The subdural window can detect thin subdural hematoma that is adjacent to the calvaria more accurately than the standard brain window.

Case Discussion

The subdural window can detect shallow subdural hematoma that is adjacent to the calvaria more accurately than the standard brain window. It uses a wider setting than the standard brain window.
