<b>Background and Objective</b> Supplementary motor area (SMA) syndrome, an executive disorder with speech dysfunctions, is rather unpredictable typically a complete or almost functional recovery within weeks months. Compensatory mechanisms are associated contralateral cortical recruitment of the lateral premotor circuitry. We sought to investigate role healthy SMA for following surgery in medial frontal lobe. <b>Methods</b> A 48-year-old right-handed man presented focal seizures. The...
Several animal experimental models have been used in the study of malignant gliomas. The objective was to test efficacy a simple, reproducible and low cost model, using human cells glioblastoma multiforme (GBM) xenotransplantated subcutaneous tissue Wistar rats, immunosuppressed with cyclosporin given by orogastric administration, controlled nonimunosuppressed rats. animals were sacrificed at weekly intervals we observed gradual growth tumor group. average volume throughout experiment 4.38...
We report two cases of complex middle cerebral artery aneurysms that were surgically treated using the orbitopterional approach in a two-piece method. The objective this work is to discuss usefulness surgical management large and giant aneurysms. A 32-year-old man with aneurysm 50-year-old woman presented subarachnoid hemorrhages. Both successfully clipped through an approach. This permits more basal view vascular structures only minor retraction frontal lobe. It also increases angle amount...
Sarcoidosis is a disease of unknown etiology presenting as noncaseating granulomatous infiltration in tissues. Central Nervous system rarely affected , usually dissemination from other organs, mainly lungs. We report on case which the patient had only central nervous involvement, with mass right gasserian ganglion and another lesion parietal cortex, observed magnetic resonance. Diagnosis was given by histopathological study improved corticosteroid treatment.
Introduction: The most frequent cause of spontaneous subarachnoid hemorrhage (SAH) is the rupture a brain aneurysm. Approximately 5% cases SAH did not show changes on magnetic resonance imaging (MRI) or angiography that explain such bleeding. objective this study was to report case induced by warfarin, where there no evidence any vascular malformation. Case Report: A 59 year-old male patient developed sudden onset severe headache while in shower. had history mitral valve disease and...
