Dexamethasone is a standard treatment for cerebral edema after brain tumor surgery. However, its side effects can negatively impact the quality and safety of care provided to patients. Sparse evidence exists in the literature regarding postoperative steroid dosing to guide clinicians. The objective of this study was to determine if a new reduced exogenous steroid taper (REST) protocol would effectively treat postoperative cerebral edema while reducing the incidence of steroid-related side effects including diabetes, hypertension, and insomnia. ⋯ A reduced steroid taper after brain tumor surgery significantly reduced the incidence of hypertension without increasing LOS or 30-day readmissions compared with controls treated with a high-dose taper.

The minimally invasive microvascular decompression (MVD) for trigeminal neuralgia is technically a more challenging operation compared with the standard retrosigmoidal approach. Endoscopic assistance could help to widen the field of view of the microscope during MVD. An extended view around the cisternal segment of the trigeminal nerve can be achieved only with the targeted dissection of the arachnoid membranes. The goal of our study was to analyze the three-dimensional organization of these membranes around the trigeminal nerve. ⋯ Knowledge of the described anatomy of the arachnoid membranes around the trigeminal nerve is essential to safely perform an MVD.

Arterial pseudoaneurysms of the neck are rarely reported in the pediatric population and no dedicated large series are available. Trauma and infection are the most common causes for these aneurysms, with congenital and collagen vascular disorders being the less common causes. These lesions can be life threatening, especially when they present with bleeding or airway compromise. ⋯ Endovascular means of treatment for pediatric neck aneurysms is relatively simple and safe. Although parent vessel sacrifice is the gold-standard management, vessel-preserving strategies can be tried in select cases with favorable anatomy.

The natural history and the outlook of patients with hydrocephalus are dramatically affected using cerebrospinal fluid shunts. The several issues related with a long-standing shunt should suffice to justify all the possible attempts to free the patient from it. This study focused on the role of secondary endoscopic third ventriculostomy (ETV) in the achievement of shunt removal in cases of shunt malfunction, and to identify patients who could benefit most from the procedure. ⋯ Many patients with shunt malfunction can benefit from secondary ETV even after decades of shunting. Age at secondary ETV, the number of previous shunt revisions, and the ETV success score can help to better identify the best candidates for the procedure.

Poor sanitation, poor hygiene, and archaic cooking practices have led to neurocysticercosis (NCC) being endemic in India. Apart from a cortical location that leads to seizures, intraventricular NCC can present with hydrocephalus and sudden deterioration in sensorium. Consequently, endoscopic excision plays an important role in its treatment because a dilated ventricle offers a minimally invasive and less traumatic route to the pathology. ⋯ An endoscopic approach is a feasible and safe tool for treating this disease. Technical nuances such as entry point and trajectory of endoscope need to be kept in mind while operating.
