RESUMO
The data about anatomic-topographic peculiarities of petroclival sub- and supratentorial meningiomas were presented. There were operated on 24 patients, of them 5 have died. Three main topographoanatomic variants were delineated, depending on the tumor primary origin and topographic peculiarities present. The most frequent variant of the tumor localization was a lower one. Depending on the variant of the tumor localization present, the peculiarities of interrelationship between the tumor and nerves, vessels and the brain stem are determined.

On the basis of observation of 65 patients with focal traumatic injury to the brain (hematoma of mater encephali was noted in 24, intracerebral--in 27, a focus of type III brain contusion--in 24, type IV--in 11, multiple hematomas and foci on contusion-crush--in 21), the criteria for their non-surgical treatment have been substantiated. Choice of a method for the treatment depends on the sizes of a hematoma, focus of contusion-crush, location of an injury, degree of its influence on the brain structures (deformation, shift), value of intracerebral pressure, dynamics of the clinico-roentgenologic symptoms.
