The miniature swine (Sus scrofa) is a desirable model for certain electrophysiological studies because of its large brain, ready availability and low cost. We report our findings regarding the location of the auditory and somatosensory cortices obtained by cortical surface evoked potential mapping. Data were collected from 11 animals under general endotracheal anesthesia. Consistent positive po...

Abstract Background The most common surgical approach in neurosurgery to diagnose and treat tumors aneurysms is the transylvian-pterional approach. classification of Sylvian fissure (SF) was proposed based on pure anatomical observations by Yasargil. SF identifiable feature superolateral brain surface, which divides parietal frontal lobes from temporal lobe lies below. Aim aim identify variatio...

A 54-year-old woman presented to the emergency department with sudden onset severe headache, nausea and vomiting upon waking that morning. On examination, she was alert and oriented, with a mild right facial droop and a right upper extremity pronator drift. A non-contrast computed tomography (CT) of the head revealed diffuse subarachnoid blood, with a prominent triangular focus projecting into ...

We report our experience with a supraorbital eyebrow minicraniotomy. This technique is suitable to lesions situated in the region of the anterior fossa, suprasellar cisterns, parasellar region and Sylvian fissure. A 50 mm incision in the eyebrow and a supraorbital minicraniotomy is performed. Sixteem patients harboring different lesions were operated on with good postoperative and cosmetic resu...

A 36-year-old female suddenly developed a severe headache. Computed tomography demonstrated subarachnoid hemorrhage in the left Sylvian fissure. Left carotid angiography revealed a fenestration at the distal portion of the M1 portion of the left middle cerebral artery, and an aneurysm arising from the proximal end of the fenestration. These findings were confirmed when the aneurysm neck was cli...

A focal aphasic syndrome was the first and outstanding manifestation of a degenerative, presenile dementia in a 67 year old man. Computerised axial tomography showed a strikingly dilated left Sylvian fissure--particularly in its posterior aspect--in the presence of moderate diffuse cortical atrophy. The radiographic findings correlated well with the clinical data. This is the first report of an...
