Case Discussion
This case demonstrates the blend sign of intracranial hemorrhage. This blend sign is a useful predictor for hematoma growth following intracerebral hemorrhage, as is demonstrated in this case.
The blend sign is defined as 1:
intracranial hematoma with two different density components identifiable by the naked eye
difference between the two densities >18 HU
the hypoattenuating component is not encapsulated by the hyperattenuating region
