There is an associated right frontotemporal extradural hematoma that causes mass effect over the adjacent brain and midline shift.

A subgaleal hematoma is also present along the right frontotemporal portion of the calvaria.

Case Discussion

This case shows the classic appearance of an acute extradural hemorrhage in a young patient involved in a head strike. This hematoma represents a collection of blood that forms between the inner surface of the skull and outer layer of the dura (which is the periosteum), it is a subperiosteal hematoma located on the inside of the skull. 

The patient was submitted to a prompt neurosurgery evacuation of the hematoma.
