Multiple primary neoplasms are defined as multiple occurrences of malignant neoplasms of differing histological origin in the same individual. The present study describes the case of a 46-year-old male who suffered from two synchronous primary malignant neoplasms, an osteoclastoma of the left femoral trochanter and an anaplastic astrocytoma of the the Sylvian fissure area in the brain. At the 6...

A transsylvian approach to treat aneurysms located at the bifurcation/trifurcation of the middle cerebral artery (MCA) is described. This surgical route traces a distal MCA branch retrogradely into the Sylvian fissure whereupon a secondary MCA branch and the main stem of the MCA (M1) are identified before aneurysm clipping. The advantages, and disadvantages of this approach are discussed. The t...

We report a rare case of intradural primary osteosarcoma (IPOS) in a 74-year-old man with aphasia and right-sided hemiparesis. Radiologic workup revealed a large, partially calcified, left-sided frontotemporal intracranial mass lesion. At surgery, the tumor was found to be entirely intradural; it involved the brain and subarachnoid space of the left sylvian fissure. The adjacent dura was uninvo...

Abstract Introduction Accurate manoeuvring of the Sylvian fissure borders to provide an optimal operating corridor is vital for minimising retraction. The anatomy can pose technical challenges impacting overall success procedure. Yaşargil previously proposed a classification distinguishing four anatomical variants correlating with surgical difficulty. We aim utilise open-source Human Connectome...

Cortical areas that control ear movement have not been reported in humans. We describe a rare case in which ear auricle movement was induced by extraoperative electrical cortical stimulation. A 21-year-old man with intractable localization-related epilepsy was admitted for presurgical evaluation. Subdural electrodes were implanted over the right temporal and frontal regions. Tonic upward contra...
