[The results of computed tomography in patients with traumatic epilepsy].

Computerized tomography in 134 patients with traumatic epilepsy allowed to reveal different changes in the brain tissue, meninges and CSF spaces. Early stages were characterized by signs of meningeal adhesions. With increased duration of the disease these changes were supplemented by signs brain atrophy in the form of dilatation of the subarachnoidal spaces, internal hydrocephalus. CSF cysts were diagnosed in 5 patients, porencephaly in 2, ischemia foci in the brain in 9 patients.

[Status of cerebral ventricles and meninges in subarachnoid hemorrhage (clinico-pathomorphological studies)].

Long-term investigation of 64 patients with subarachnoidal hemorrhages (SH), 24 of which had subsequently died, and 2 series of experiments of animals with a single or repeated intracysternal infusion of various doses of autologous blood, yielded the description of the response of the meninges and ventricles at different terms after SH. The brain ventricles were measured by axial computer tomography and echoencephalography. A index of CSF resorption resistance and CSF pressure were determined. The cerebral meninges from experimental animals and autopsied human ones underwent the histological examination. The authors discuss the mechanisms of development of liquor dynamic disorders at different terms after SH.

[Computed tomography of the brain in suppurative meningoencephalitis].

The studies made showed that one-tenth patient with purulent meningoencephalitis (PME) needs to be examined by axial computerized tomography (ACT) techniques. The following items are indications for ACT: apparent or progressive neurological symptomatology, protracted or relapsing course of PME, formation of the intracranial liquor hypertension, apparent changes in echoencephalography, and congestive disorders in the eyegrounds. Brain ACT permits finding a relevant policy of treating patients (surgery or conservative option) together with predicting the course and outcome of PME.

[Agenesis of the corpus callosum].

Clinical follow-up of 9 patients with agenesis of the corpus callosum is analysed. It is established that the pleomorphism of the clinical manifestations in agenesis of the corpus callosum is determined by the concomitant cerebral lesions. Pneumoencephalography should be considered the method of choice in the diagnosis of agenesis of the corpus callosum because it demonstrates the changes in the ventricular system characteristic of this anomaly and the changes in the cerebrospinal fluid channels attendant to it. A decrease in the distance between the inferior sagittal sinus and the internal cerebral vein and in the distance between the pericallosum artery and the internal cerebral vein are pathognomonic angiographic signs. No pathognomonic changes in the bioelectric activity of the brain in agenesis of the corpus callosum were detected.

[The characteristics of computed study data on the brain in viral meningoencephalitis].

An analysis is presented of CT examination of the brain in viral meningoencephalitis in 113 patients with viral encephalitis. Pathological changes in the acute period were found in 65.4% of patients more frequently in the CSF system, rarer in the brain tissue (in herpetic encephalitis). During the early convalescence period 75% of patients showed dilated ventricles and external CSF spaces. The importance of CT examination in this kind of pathology is emphasized.
