[Diagnosis and phasic character of the course of the midbrain syndrome secondary to acute intracranial hematoma].

Thirty patients with acutely developed intracranial hematomas of traumatic and nontraumatic origin were subjected to a combined examination. In all cases, cerebral angiography was performed and evoked auditory trunk potentials were studied. Comparison of the resultant findings with the data from a clinical-neurologic and echoencephalographic examinations and also with pathomorphological evidence made it possible to identify new diagnostic criteria for determining an acute dislocation syndrome at the temporal-tentorial level, particularly for the purpose of detecting cerebral infiltrations.
