Foramen magnum meningioma approached by the midline subtonsilar approach - Revisiting Cushing's classification of craniospinal meningiomas.

Background: The management of foramen magnum meningiomas (FMMs) has been a challenge for skull base neurosurgeons. Since the initial description of a FMM in 1872, various surgical approaches have been described. Posterior and posterolateral FMMs are safely removed through a standard midline suboccipital approach.

Decompressive Hemicraniectomies as a Damage Control Approach for Multilobar Firearm Projectile Injuries: A Single-Center Experience.

Background: While firearms projectile injuries to the head carry a high rate of morbidity and mortality, current literature in clinical management remains controversial. Decompressive hemicraniectomy (DHC) has been previously described in the neurosurgical literature for traumatic brain injuries, with positive results in the reduction of mortality. Here we aim to assess DHC as a damage control approach for multilobar firearm injuries to the head and compare our results with what is present in the literature.

Minimally invasive craniotomies for lesions of the anterior and middle fossa.

Minimally invasive craniotomies are the subject of increasing attention over the last two decades in neurosurgery, following the current trend of attempting to increase patient safety by providing surgeries with less tissue disruption, blood loss, and decreased operative time. However, a significant information overlap exists among the various keyhole approaches regarding their indications and differences with more invasive techniques. Therefore, the present study aims to comprehensively review, illustrate, and describe the potential benefits and disadvantages of minimally invasive techniques to access the anterior and middle fossa, including the mini-pterional, mini orbito-zygomatic, supraorbital, lateral supraorbital, and extended lateral supraorbital approaches while comparing them to classic, more invasive approaches.

A Giant Internal Carotid Bifurcation Aneurysm as a Rare and Dangerous Differential Diagnosis of a Craniopharyngioma.

Craniopharyngiomas are supra/parasellar lesions that often present with general, unspecific symptoms. Similarly, internal carotid artery (ICA) bifurcation giant aneurysms may also produce calcified, heterogeneous, parasellar expansive lesions, posing a relevant differential diagnosis due to their inherently different surgical strategies and risks. We report the case of a 54-year-old female presenting with progressive disorientation and apathetic behavior.

Microsurgical resection of a giant cervico-medullary ependymoma: 2D-dimensional video.

Background: Ependymoma is a slowly growing benign neoplasm that constitutes 3-9% of all neuroepithelial spinal cord tumors.[3,4] They rarely involve the cervicomedullary junction where they both compress the distal brainstem and upper cervical cord. Due to the critical contiguous structures, gross total resection of these lesions may result in significant morbidity/mortality.
