The exact diagnosis can be achieved only with the CT scan that will show no mass effect in a comatose patient with decerebrate and decorticate pusture. Very often hypertermia, hypertension and sweating occur. Cerebral concussion means temporary disruption in cerebral activity resulting from injury, reflected in transiently altered consciousness or other temporary loss of neural function. Linear fractures of the skull usually are usually clearly visible at x ray film. If linear fracture is present, suspected an arterial epidural haematoma in an adult if the fractures crosses any branch of the middle meningeal artery, a venous epidural haematoma if the fracture crosses the superior longitudinal or lateral sinus, and a diploic epidural haematoma if there is a large separation of fracture bone fragments in an infant.
Careful observation is indicated.
The ear canal should not be packed since it might hinder egress of fluid or blood. X ray diagnosis is often difficult, even with CT scan. Sometimes a surgical intervention is required to close a CSF leak. Intracerebral haematoma may result from acute injury or progressive damage secondary to contusion. This haematoma should be removed.
