The complex clinical and radiation examination was made in 135 victims with craniocerebral trauma and in 120 patients with primary tumors of the brain. All observations evaluated the index of transversal dislocation of the brain. It included derivative of volume parameter of intracranial supratentorial substratum, the value of dislocation of ventricular system and its width relatively to the septum pellucidum and at the same time the state of mind according to Glasgow coma scale. High diagnostic informativity of developed and certified index of transversal dislocation in different intracranial pathology allowed using the index for more wide application.
