Systemic Immune-Inflammation Index Predicts Acute Symptomatic Hydrocephalus After Spontaneous Nonaneurysmal Subarachnoid Hemorrhage.

Objective: The authors sought to investigate the association between white blood cell counts and acute hydrocephalus in spontaneous nonaneurysmal subarachnoid hemorrhage (nSAH).

Methods: We conducted a retrospective analysis of 105 consecutive patients with spontaneous nSAH. Univariate and multivariable logistic regression analyses were performed to investigate factors associated with hydrocephalus.

Monocyte Count on Admission Is Predictive of Shunt-Dependent Hydrocephalus After Aneurysmal Subarachnoid Hemorrhage.

The authors sought to evaluate whether immunologic counts on admission were associated with shunt-dependent hydrocephalus following aneurysmal subarachnoid hemorrhage. A retrospective analysis of 143 consecutive patients with aneurysmal subarachnoid hemorrhage over a 9-year period was performed. A stepwise algorithm was followed for external ventricular drain weaning and determining the necessity of shunt placement.

Perimesencephalic Subarachnoid Hemorrhage Has a Unique Peripheral Blood Leukocyte Profile Compared To Aneurysmal Subarachnoid Hemorrhage.

Objective: The authors sought to investigate if peripheral blood leukocyte profiles on admission differed between perimesencephalic, angio-occult, and aneurysmal subarachnoid hemorrhage cohorts.

Methods: We performed a retrospective analysis of 202 consecutive patients with spontaneous subarachnoid hemorrhage. We classified spontaneous subarachnoid hemorrhage as either aneurysmal or nonaneurysmal origin.

Initial intracranial pressure is an independent predictor of unfavorable functional outcomes after aneurysmal subarachnoid hemorrhage.

The authors sought to evaluate whether initial intracranial pressure was associated with functional outcomes following aneurysmal subarachnoid hemorrhage. This retrospective analysis consisted of 54 consecutive patients with aneurysmal subarachnoid hemorrhage and acute symptomatic hydrocephalus requiring emergent placement of an external ventricular drain. Patient demographics, clinical data, intracranial pressure parameters, and radiographic imaging were collected.

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.

Case Report: Metastatic Bronchopulmonary Carcinoid Tumor to the Pineal Region.

Intracranial spread of a systemic malignancy is common in advanced staged cancers; however, metastasis specifically to the pineal gland is a relatively rare occurrence. A number of primary lesions have been reported to metastasize to the pineal gland, the most common of which is lung. However, metastasis of a bronchial neuroendocrine tumor to the pineal gland is a seldom-reported entity.

Factors affecting R01 grant funding among academic neurosurgeons over the last decade.

Background: Recent studies have reported a gender and medical degree disparity for those receiving Research Project Grants in surgical specialties. The aim of the present study is to analyze factors among academics neurosurgeons that correlate to higher amounts of R01 grant monies awarded.

Materials And Methods: The National Institutes of Health Research Portfolio Online Reporting Tools Expenditures and Results database was queried for neurosurgery funding between 2008 and 2018.

Spontaneous necrotizing granuloma of the cerebellum: a case report.

Background: Intracranial necrotizing granulomatous space-occupying lesions are sparsely reported in literature. Variability in presenting symptomatology and radiographic features makes diagnostic work-up difficult.

Case Presentation: This report presents the case of a 77-year-old female with sinusitis and fatigue who underwent an MRI revealing a posterior fossa lesion compressing the fourth ventricle.

Recurrent Cerebral Vasospasm and Delayed Cerebral Ischemia Weeks Subsequent to Elective Clipping of an Unruptured Middle Cerebral Artery Aneurysm.

Background: Cerebral vasospasm and delayed ischemic neurologic deficits are well-known clinical aftereffects of subarachnoid hemorrhage due to rupture of an intracranial aneurysm. However, vasospasm with consequential ischemia after clipping of an unruptured aneurysm is an exceedingly rare sequela encountered in the reported neurosurgical literature.

Case Description: A 53-year-old woman had presented for elective craniotomy with microsurgical clipping of an unruptured left middle cerebral artery bifurcation saccular aneurysm, which was successfully treated without complications.

N-butyl cyanoacrylate embolization of a traumatic pseudoaneurysm and arteriovenous fistula of the middle meningeal artery.

We report a case of combined traumatic pseudoaneurysm and arteriovenous fistula of the middle meningeal artery, which presented clinically 1 year after initial head trauma. A 39-year-old male presented with seizure activity after a closed head injury from a fall. He was hospitalized for multiple intraparenchymal hemorrhages and ultimately discharged 2 weeks later without neurologic deficits.

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.

Rapidly fatal encephalitis associated with atypical lymphoid proliferations of the basal ganglia subsequent to aneurysmal subarachnoid hemorrhage.

Rapidly fatal encephalitis associated with atypical lymphoid proliferations after intracranial aneurysm rupture has not been reported. Here, we describe a 52-year-old female who presented to the emergency department with a severe headache. Imaging demonstrated aneurysmal subarachnoid hemorrhage due to a ruptured left posterior inferior cerebellar artery aneurysm, which was treated with endovascular embolization and subsequent external ventricular drain.

Short- and Long-Term Geriatric Mortality After Acute Traumatic Subdural Hemorrhage.

Background: Acute subdural hemorrhage often occurs in those ≥65 years of age after trauma and tends to yield poor clinical outcomes. Previous studies have demonstrated a propensity toward high in-hospital mortality rates in this population; however, postdischarge mortality data are limited. The objective of the present study was to analyze short- and long-term mortality data after acute traumatic subdural hemorrhage in the geriatric population as well as review the impact of associated clinical variables including mechanism of injury, pre-morbid antithrombotic use, and need for surgical decompression on mortality rates.

Neoplastic Cerebral Aneurysm from Metastatic Lung Adenocarcinoma with Neuroendocrine Features.

Background: Neoplastic cerebral aneurysms are exceedingly rare. We describe a case of a ruptured, distal middle cerebral artery aneurysm as the presenting symptom leading to the identification of metastatic lung cancer.

Case Description: The patient underwent an uncomplicated surgical trapping and ligation of the aneurysm.

Quantitative Description of Osteopathic Physician Authorship in Prominent Neurosurgery Journals Since 1944: Coming of Age?

Background The Accreditation Council for Graduate Medical Education and the American Osteopathic Association recently agreed to establish a single graduate medical education system for the United States allopathic and osteopathic resident physicians by 2020. Consequential to this merger, new standards will be implemented for academic and research requirements within medical schools as well as residency programs. In the United States, osteopathic medicine is considered to be a parallel profession to allopathic medicine.
