Development and Validation of a Predictive Nomogram for Patients With Myxopapillary Ependymoma: A Surveillance, Epidemiology, and End Results (SEER) Retrospective Cohort Analysis.

Study Design: Retrospective Study.

Objective: Myxopapillary ependymomas (MPEs) are a unique subgroup of spinal ependymomas originating from the filum terminale's ependymal glia. The 2021 WHO classification reclassified all MPEs as grade 2, recognizing their higher recurrence risk.

Depressed skull fracture compressing eloquent cortex causing focal neurologic deficits.

Background: Depressed skull fractures are typically the consequence of high-impact injuries with inward buckling of the cranium. The majority of depressed skull fractures are managed conservatively in the absence of dural violation, sinus involvement, significant underlying hematoma, depressed fragment greater than 1 cm, wound infection, or gross wound contamination. Even in the presence of any of the aforementioned criteria, cranioplasty is typically considered an urgent procedure rather than a neurosurgical emergency.

Spinal Intradural Arachnoid Cysts in Adults: An Institutional Experience and Literature Review.

Background: Adult spinal intradural arachnoid cysts are rare pathologic entities with an unclear etiopathogenesis. These lesions can be dichotomized into primary (idiopathic) or secondary (related to inflammation, intradural surgery, or trauma) etiologies. Limited series have depicted optimal management strategies and clinical outcomes.

Supratentorial cortical ependymoma: A systematic literature review and case illustration.

Cortical ependymomas are currently not considered a subgroup of supratentorial ependymomas; however, there is a growing body of literature investigating the natural history of these lesions compared to supratentorial ependymomas. We performed a systematic literature review of cortical ependymomas with a focus on the natural history, clinical characteristics, and clinical outcomes of these lesions as compared to supratentorial ependymomas. Our search revealed 153 unique cases of cortical ependymomas.

Neutrophil Count on Admission Predicts Acute Symptomatic Hydrocephalus After Aneurysmal Subarachnoid Hemorrhage.

Objective: To investigate the association between immunologic counts on admission and acute symptomatic hydrocephalus after aneurysmal subarachnoid hemorrhage (aSAH).

Methods: We conducted a retrospective analysis of 143 consecutive patients with aSAH. Patient demographics, clinical parameters, laboratory values, and radiographic imaging were obtained.

Corticosteroid-Induced Regression of Glioblastoma: A Radiographic Conundrum.

Corticosteroid-induced regression of lesion contrast enhancement on imaging studies is most commonly appreciated with primary central nervous system lymphoma; however, although exceedingly rare, a limited number of primary and metastatic intracranial lesions have been reported to exhibit similar radiographic changes subsequent to corticosteroid therapy. To date, there have been six cases of glioblastoma reported to exhibit such changes. Lesion transformation on repeat imaging after the initiation of steroids represents a diagnostic dilemma for clinicians when attempting to differentiate between a diagnosis of glioblastoma and lymphoma.

Epilepsy control following intracranial monitoring without resection in young children.

Purpose: Intracranial monitoring (IM) is a key diagnostic procedure for select patients with treatment-resistant epilepsy (TRE). Seizure focus resection may improve seizure control in both lesional and nonlesional TRE. IM itself is not considered to have therapeutic potential.

Quality of life following epilepsy surgery for children with tuberous sclerosis complex.

Parents of children with tuberous sclerosis complex who underwent multistage resections for treatment of refractory seizures were offered a telephone questionnaire regarding quality of life (QOL) of child and family since surgery. Of 53 families, 39 responded. Age at epilepsy onset was birth to 3 months.
