Ganglioglioma: comparison with other low-grade brain tumors.

Method: Forty-two patients with low-grade brain tumor and refractory epilepsy were studied. The mean age was 22.3 years.

Traumatic pseudoaneurysm of the middle meningeal artery and cerebral intraparenchymal hematoma: case report.

Background: Pseudoaneuryms of the MMA are rare lesions, accounting for less than 1% of all intracranial aneurysms.

Case Description: We report a case of a spontaneous intracerebral hematoma that DSA revealed as ispilateral traumatic PMMA. The lesion was managed through an endovascular approach, and definitive embolization of pseudoaneurysm and parent vessel with histoacryl injection was carried out.

[Neurological manifestations of dengue: study of 41 cases].

Unlabelled: The increase of encephalitis and meningoencephalitis in patients with dengue, diagnosed at a public hospital, Neurology State reference, we adopted systematic data collection.

Objective: The objective was to present 41 cases of neurological manifestations of dengue and to compare data with literature.

Method: This is a descriptive study, retrospective from March to July 1997 and, prospective, from February to May 2002, analyzing damaged neurological regions and diagnostic of 41 patients.

[Intraoperative mapping of motor areas during brain tumor surgery: electrical stimulation patterns].

Unlabelled: Brain mapping with direct electrical stimulation is usefull when the tumor is located near or has infiltrated the central lobe.

Objective: To analyze the surgical findings with direct electrical stimulation of the cortex and white matter under general anesthesia during surgery for brain tumors related to the central lobe.

Method: We studied 42 patients operated on from June 2000 to June 2003.

[Epidemiology of 118 cases of multiple sclerosis after 15 years of follow-up on the reference center of Hospital da Restauração, Recife, Pernambuco, Brazil].

Unlabelled: The prevalence of multiple sclerosis (MS) has a considerable variability all over the world. According to Kurtzke, South America is considered to have low prevalence (minor than 5 cases: 100000 habitants).

Objective: To describe the MS epidemiology on a reference center, compared to eight Brazilian series.

[Partial epilepsy associated to primary brain tumors].

Objective: To characterize the epileptic syndrome of patients with primary cerebral tumor of slow growth.

Method: Clinical evaluation of fourty two patients with refractory epilepsy associated with cerebral tumor of slow growth were operated between June 1992 and September 1999.

Results: Almost 75% of the patients were less than 15 years old when they began the epileptic crises, 67.

Progression of an arterial infundibulum to aneurysm: case report.

In this case an aneurysm of the right posterior communicating artery developed 11 months after an infundibular dilation of this artery had been angiographycally and surgically demonstrated. In the best of the authors' knowledge, there are only eleven such cases reported in the literature. This report brings about diagnostic and therapeutic questions regarding arterial infundibula and the need of a better understanding of those lesions.
