Surgical therapy for frontal epilepsies.

We have described our 25 years experience concerning 100 patients operated on for frontal epilepsy. Results show that 55% of patients are practically cured of their seizures and that 76% benefited from cortectomy (reduction of more than 75% of seizures). These results are the worst in the total series of St.

[Current significance of stereotactic exploration in the diagnosis and therapy of space-occupying cerebral processes].

To reach good functional results in patients with spaceoccupying processes--especially with those localized in the dominant hemisphere operative treatment should be planned individually, which is impossible if all diagnostic assessments are followed by the same surgical procedure. The choice of appropriate method of therapy in case of brain tumor depends on various factors, such as the histological nature, extent and volume, relationship to the brain structures and vessels, and spatial form of the growth. The synthesis of all neuroradiological information from stereotactic exploration, together with the histological findings from stereotactic serial biopsies yields a three-dimensional representation of the brain with the tumor.

[Acute transient Korsakoff's syndrome caused by hematoma of the floor of the 3rd ventricle].

A forty four year-old woman had had an amenorrhea-galactorrhea syndrome for 3 months when a Korsakoff's syndrome with headache suddenly appeared. Neuroradiological investigations revealed a hematoma involving the anterior part of the IIIrd ventricle. After a short period of neurogenic hypernatremia the lesion disappeared with the development of a spontaneous ventriculocisternostomy.

[Familial forms of intracranial cavernous hemangioma. Apropos of 5 cases in 2 families].

The authors report five cases of cavernous hemangioma belonging to two families. In the first family, an 8 year old child was operated on in 1970 for a left frontal location. His mother, aged 39, was operated on in december, 1981, with stereotaxic approach, for two locations: one was frontal location, the other one was in the pineal region.
