Foramen magnum meningiomas (FMM) represent a challenge for neurosurgeons. These tumors require careful surgical manipulation as they are often located in proximity to critical neurovascular structures and the cranial nerves. The far lateral approach is considered the safest neurosurgical approach for excising foramen magnum lesions. It facilitates the access to the anterior foramen magnum and reduces the retraction of vital structures. We describe key historical, epidemiological, genetic, epigenetic, clinical, and neurosurgical aspects of FMM...

OBJECTIVE: In neurotrauma care, a better understanding of treatments following traumatic brain injury (TBI) has led to a significant decrease in morbidity and mortality in this population. TBI represents a significant medical problem, and complications following TBI are associated with the initial injury and post-event intracranial processes such as elevated intracranial pressure (ICP) and brain edema. Consequently, appropriate therapeutic interventions are required to reduce brain tissue damage and improve cerebral perfusion...

INTRODUCTION: Pure choriocarcinoma of the testes is a rare, aggressive germ cell tumor (GCT) that can metastasize to the brain. Although its prognosis has improved with the development of cisplatin-based chemotherapy regimens, cerebral metastases are prone to hemorrhage and are associated with high morbidity. Here, we present two cases of testicular choriocarcinoma with cerebral metastasis and discuss potential pitfalls in their diagnosis and management. We also review cases in the literature that feature these rare lesions...

BACKGROUND: Simulation-based education has made its entry into surgical residency training, particularly as an adjunct to hands-on clinical experience. However, one of the ongoing challenges to wide adoption is the capacity of simulators to incorporate educational features required for effective learning. The aim of this study was to identify strengths and limitations of spine simulators to characterize design elements that are essential in enhancing resident education. METHODS: We performed a mixed qualitative and quantitative cohort study with focused survey and interviews of stakeholders in spine surgery pertaining to their experiences on three spine simulators...

The purpose of this historical review is to summarize the most significant theories on the cause of death of King Henry II of France (1519-1559) and the circumstances under which it occurred. Although the testimonies are inconclusive and vague, post mortem analysis showed that the cause of death of the King was meningoencephalitis, caused by haematoma of cerebral contusion, with effusion in the cerebral laminae, in its surrounding tissue initiated from a periorbital fracture.

Primary spontaneous cerebrospinal fluid (CSF) rhinorrhea due to clival defect is an extremely rare presentation and only six cases have been reported in the literature so far(17). We present a unique case of a 64-year-old lady who presented with 2 years history of ongoing CSF rhinorrhea. She had similar episode at the age of 40 and suffered from meningitis. She had MRI, CT cisternogram as well as CT of brain and that showed clival defect with CSF leak into the sphenoid sinus. She underwent trans-sphenoidal repair of the clival defect with concurrent lumbar drain insertion for CSF drainage...
