Schwannomas of the Frontal Sinus: Cases and Review of the Literature
We report two patients with schwannomas originating in the frontal sinus, with variable degrees of extension. These patients underwent resection of the tumors via an endoscopic or combined approach. The histological diagnosis confirmed schwannoma. Though these lesions have traditionally been approached through larger craniotomies and open procedures, these cases represent less invasive approaches for these rare frontal sinus schwannomas, and demonstrate them as a valid alternative with minimal morbidity for the patient.

Surgical Treatment of Mirror MCA Aneurysms: Bilateral and Unilateral Approach
Currently, the optimal surgical approach for bilateral aneurysms remains controversial. Alternative interventional methods, such as unilateral or bilateral approaches, have been employed during a single session or two different sessions. The unilateral approach can be employed successfully to treat contralateral aneurysms that develop in a paramedian location. However, such an approach is more difficult for treating contralateral aneurysms in more distant locations. Unilateral approach can decrease complication rates, operation time and the length of hospital stay. (Source: World Neurosurgery)

Impact of symptomatic metastatic spinal cord compression on survival of patients with non-small cell lung cancer
Non-small cell lung cancer (NSCLC) is one of the most common primary tumor site among patients with metastatic spinal cord compression (MSCC). This disorder is related to neurological dysfunction and can reduce the quality of life, but the association between MSCC and death is unclear. The aim of this study was to analyse the impact of the occurrence of symptomatic MSCC on overall survival (OS) of patients with NSCLC. (Source: World Neurosurgery)

Clinical Outcomes with Transcranial Resection of Tuberculum Sellae Meningioma
The tuberculum sellae is a relatively common location for meningiomas. We assessed our experience with the use of the transcranial resection, which, while criticized for its more invasive nature compared with endonasal approaches, may be the ideal approach in selected patients with tuberculum sellae meningiomas (TSMs).

Severe cerebral complications secondary to perforation injury of the anterior skull base during sinonasal surgery: an underappreciated problem?
Functional endonasal sinus surgery (FESS) is widely practiced and is considered a generally safe procedure. Skull base injuries occur in less than 1% of procedures and are typically associated with cerebrospinal fluid leaks. Rarely, skull base injuries might result in cerebral lesions. Here we present a series of four patients with iatrogenic perforating injuries of the anterior skull base and cerebral lesions after routine FESS. (Source: World Neurosurgery)

Giant Cell Ependymoma of the Lateral Ventricle: Case Report, Literature Review, and Analysis of Prognostic Factors and Genetic Profile
We report a case of GCE arising in the lateral ventricle. A 22-year-old female presented with generalized seizures. MRI demonstrated a diffuse, non-enhancing, multi-cystic mass centered in the atrium of the right lateral ventricle with extension throughout the frontal and temporal horns. An initial subtotal resection yielded the signature biphasic pattern of GCE. The dominant component contained pleomorphic, bizarre-appearing giant cells with low mitotic index, and a minor component comprised monomorphic, highly cellular, mitotically active cells that formed perivascular pseudorosettes.

Chronic Subdural Hematoma: a Perspective on Subdural Membranes and Dementia
Chronic subdural hematoma (cSDH) is a common intracranial pathology, and a leading cause of reversible dementia. cSDH is projected to affect at least 60,000 new individuals in the United States annually by 2030.This can result from mild to moderate head trauma that leads to hemorrhaging in the dura-arachnoid interface. The short and long-term effects of cSDH and the subdural membrane on the pathogenesis of dementia and the newly discovered dural lymphatics is a topic of increasing importance. This manuscript aims to review the complex pathogenesis of the subdural membrane, and the link between head trauma, dementia, and du...

Chronic subdural hematoma (cSDH) affects 1-5.3 per 100,000 individuals annually, with the incidence expected to rise as the U.S. population ages. The symptoms of cSDH are often nonspecific, with headaches being the most common complaint. Other symptoms include weakness, balance and gait problems, and memory problems. A variety of clinical factors must be taken into account in the treatment of cSDH, and the multifaceted treatment paradigms continue to evolve. This review aims to highlight the clinical complexity of cSDH, while presenting a brief historical discussion of cSDH. (Source: World Neurosurgery)

Reading Between the Joints —Using Spinal Magnetic Resonance Imaging for Evaluation of Instability
Magnetic resonance imaging (MRI) is one of the most common investigations ordered for the evaluation of back and leg pain. Usually, supine MRI is one of the initial tests for the screening of degenerative spine diseases and lumbar spinal stenosis. It is useful for assessing disease severity, involvement of the spine and its surrounding structures, and making decisions about surgery. With all of these advantages in hand, the role of MRI is considered limited in a few aspects —one is the determination of instability. (Source: World Neurosurgery)
