Randomized Controlled Trial Comparative Study
Prone versus sitting position in neurosurgery - differences in patients' hemodynamic management.
Neurosurgery in general anesthesia exposes patients to hemodynamic alterations in both the prone and the sitting position. We aimed to evaluate the hemodynamic profile during stroke volume-directed fluid administration in patients undergoing neurosurgery either in the sitting or the prone position. ⋯ The sitting position does not require excess fluid treatment compared with the prone position. HES is slightly more effective than RAC in achieving comparable hemodynamics, but the difference might be explained by patient weight. With goal-directed fluid administration and moderate use of vasoactive drugs, it is possible to achieve stable hemodynamics in both positions.

Risk of delayed cerebral ischemia (DCI) in patients with aneurysmal subarachnoid hemorrhage (aSAH) with asymptomatic angiographic vasospasm on admission is unclear in the literature. The goal of this study is to identify predictors of clinical DCI in this group of patients. ⋯ Asymptomatic angiographic vasospasm in patients with good-grade aSAH on admission is uncommon. Further studies are needed to identify high-risk patients for the development of DCI in the context of asymptomatic early vasospasm.

The oncogenesis and biologic behaviors of benign glandular schwannoma have not been clinically unveiled because of its rarity and variability. ⋯ Therefore, the morphologic and immunohistochemical findings support the diagnosis of benign glandular schwannoma.

Review
Intraventricular Meningiomas: A Series Of 42 Patients at a Single Institution and Literature Review.
Primary intraventricular meningiomas (IVMs) make up 0.5%-5% of all intracranial meningiomas and represent one of the most challenging lesions in neurosurgery. ⋯ IVMs usually reach a large size before being diagnosed. Surgical treatment is the most suitable option and total removal should represent the main goal of the procedure. The posterior parietal transulcal approach and the temporoparietal approach are the most common surgical routes used in our series.

Long-term Survival Primary Intracranial Plasmablastic Lymphoma: Case Report and Review of the Literature.
Primary intracranial plasmablastic lymphoma (PIPBL) is a rare malignant tumor. ⋯ This study provides important clinical information for the diagnosis and treatment of PIPBL.
