title: [Method of unidimensional echolocation of the cerebral aqueduct and upper portions of the 4th ventricle in healthy subjects and in pathology].
abstract: The authors suggest a method of unichamber echo location of the aqueduct and upper parts of the fourth ventricle by means of which it is possible to determine displacement of these parts of the c.s.f. system in a plane close to the frontal plane in development of a volumetric focus in the posterior cranial fossa. The value of the method in making the diagnosis of a surgical pathological condition in the posterior cranial fossa is almost the same as the value of unichamber echo diagnosis of supratentorial processes.
