We present our clinical experience and the results of surgical management with 25 cavernomas of the CNS, treated in our hospital in the last 10 years. The location of the lesion assessed by clinical and CT scan examinations, proved to be the most significative factor determining the prognosis of cavernomas of the CNS, after surgical removal. The symptoms(More)
Clinical and surgical results in 38 cases of posterior fossa meningiomas are presented. All cases have been diagnosed and operated upon during the last 12 years in this department. We have identified five locations for these tumors: cerebellopontine angle, cerebellar convexity, tentorium, peritorcular, and clivus. Clinical features of these tumors and their(More)
A series of 6 patients with arachnoid cysts of the posterior fossa who were treated surgically is presented. The diagnosis of the nature of the lesion and of the exact location within the posterior fossa could not be established on a clinical basis. CT scanning is the best method for diagnosing the lesion and for observing the postoperative evolution.(More)
Different groups worldwide have observed in recent years that stereotactic implantation of fetal tissue can ameliorate the clinical symptoms of Parkinson's disease.

The clinical picture included seizures in 50% of the cases and a brain tumor-like syndrome in 37.5%, and 12.5% of the cases began with an intracerebral hemorrhage. In our(More)
The cellular changes in the neighbourhood of an alumina cream epileptogenic focus and in the mirror focus in chronic experiments in cats have been studied. According to the neuroglial morphology, four layers are described around the alumina cream lesion. At an ultrastructural level, and increase in gap junctions with a great amount of gliofilaments in(More)
