Spontaneous subarachnoid hemorrhage (SAH) is a specific characteristic of aneurysmal rupture. SAH coexisting with arteriovenous malformations challenging to treat because the patient status at admission severe and therapeutic approach multidisciplinary: endovascular treatment, cerebral fluid drainage, decompressive craniectomy. We report clinical case successfully treated for cerebellar due rup...

BACKGROUND AND PURPOSE Although neuroimaging plays an important role in the diagnosis of idiopathic normal pressure hydrocephalus, its predictive value for response to shunt surgery has not been established. The purpose of the current study was to identify neuroimaging markers that predict the shunt response of idiopathic normal pressure hydrocephalus. MATERIALS AND METHODS Sixty patients wit...

Developmental research, as well as paediatric clinical activity crucially depends on non-invasive and painless brain recording techniques, such as electroencephalography (EEG), and near infrared spectroscopy (NIRS). However, both of these techniques measure cortical activity from the scalp without precise knowledge of the recorded cerebral structures. An accurate and reliable mapping between ex...

BACKGROUND Neurofibromatosis type 1 (NF-1) is associated with learning disabilities and cognitive impairment in childhood and adolescence. Individuals with NF-1 have a propensity for brain hyperintensities on T2-weighted magnetic resonance images, macrocephaly, and optic gliomas. Few clear relationships between these central nervous system abnormalities and cognitive function, however, have bee...

INTRODUCTION Intracranial dermoid cystic tumors account for <1% of all intracranial masses. CASE REPORT A 52-year-old male, having headaches, nausea and is presented with a history of 2 episodes of new onset seizures. On presentation, the patient had a normal physical exam, including a complete neurological and cranial nerve exam. METHODS Precontrast MRI; TSE/T2Wsequence in axial/coronal pl...

My Teacher Professor Yasargil is very famous doctor, mentor, surgeon, lider, scientist, researcher, inventor and teacher of last Century, not only in Neurosurgery, but also in Neuroscience of the World. His very important Neurosurgical Way and thecniques, the pterional trans Sylvian approach, I called as “Yasargil Higway” is commonly employed in surgery of the anterior circulation and upper bas...

During the last trimester of human pregnancy, the cerebral cortex of foetuses becomes greatly and quickly gyrified, and post-mortem studies have demonstrated that hemispheres are already asymmetric at the level of Heschl gyrus, planum temporale and superior temporal sulcus (STS). Recently, magnetic resonance imaging (MRI) and dedicated post-processing tools enabled the quantitative study of bra...

BACKGROUND AND PURPOSE CSF volumes in the basal cistern and Sylvian fissure are increased in both idiopathic normal pressure hydrocephalus and Alzheimer disease, though the differences in these volumes in idiopathic normal pressure hydrocephalus and Alzheimer disease have not been well-described. Using CSF segmentation and volume quantification, we compared the distribution of CSF in idiopathic...

BACKGROUND Precise localization of an epileptic focus in the perisylvian/insular area is a major challenge. The difficult access and the high density of blood vessels within the sylvian fissure have lead to poor coverage of intrasylvian (opercular and insular) cortex by available electrodes. OBJECTIVE To report the creation of a novel electrode designed to record epileptic activity from both ...

During the second trimester, the human fetal brain undergoes numerous changes that lead to substantial variation in the neonatal in terms of its morphology and tissue types. As fetal MRI is more and more widely used for studying the human brain development during this period, a spatiotemporal atlas becomes necessary for characterizing the dynamic structural changes. In this study, 34 postmortem...
