Endoscopic Resection of Right Petrous Meningioma Causing Trigeminal Neuralgia: "The Double Crush" Phenomenon.

Trigeminal neuralgia (TN) is typically caused by neurovascular compression (NVC) at the root entry zone, often involving the superior cerebellar artery. Occasionally, TN may be secondary to cerebellopontine angle (CPA) tumors, such as meningiomas, vestibular schwannomas, or epidermoid cysts. When both a tumor and a vascular loop contribute to nerve compression, the resulting, as we refer to the "double crush" phenomenon, complicates surgical management and necessitates a more comprehensive therapeutic strategy.

Iatrogenic pseudoaneurysm formation of the anterior cerebral artery following placement of an external ventricular drain: illustrative case.

Background: External ventricular drains (EVDs) provide an invaluable diagnostic method for accessing cerebrospinal fluid and therapeutically treating elevated intracranial pressure. Although complications including hemorrhage and infection have been well documented, the formation of iatrogenic pseudoaneurysms following EVD placement has rarely been reported. The authors present a case of this exceedingly rare complication of iatrogenic pseudoaneurysm formation following EVD placement.

Multicenter and prospective trial of anti-epileptics for early seizure prevention in mild traumatic brain injury with a positive computed tomography scan.

Background: Posttraumatic seizures (PTSs) are a major source of disability after traumatic brain injury (TBI). The Brain Trauma Foundation Guidelines recommend prophylactic anti-epileptics (AEDs) for early PTS in severe TBI, but high-quality evidence is lacking in mild TBI.

Methods: To determine the benefit of administering prophylactic AEDs, we performed a prospective and multicenter study evaluating consecutive patients who presented to a Level 1 trauma center from January 2017 to December 2020.

Resection of Brainstem Cavernous Malformations: Pearls and Pitfalls for Minimizing Complications.

Background: Surgical management of brainstem cavernous malformations (CMs) is a controversial topic in the field of neurosurgery. These lesions have a propensity to hemorrhage, thereby disrupting surrounding brainstem eloquence.

Methods: This article provides the personal reflections of the senior author and a narrative literature review on resection of brainstem CMs.

Comparison of Lumbar and Ventricular Cerebrospinal Fluid for Diagnosis and Monitoring of Meningitis.

Severe meningitis, especially basilar meningitis, can lead to hydrocephalus requiring external ventricular drain (EVD) placement. There are differences in cerebrospinal fluid (CSF) obtained from an EVD compared to a lumbar puncture (LP). Hence, it becomes difficult to compare LP and EVD samples for diagnosis and monitoring of meningitis.
