Central neurocytoma (CN) is a rare central nervous system tumor the optimal management strategy of which remains controversial because of their rarity. Detailed information on CN is necessary to establish optimal management strategies. The purpose of this study was to show the clinical features, treatments, and long-term clinical outcomes of CN. ⋯ CN is a rare type of World Health Organization grade II primary brain tumor with a tendency to recur. Complete resection of CNs with maximal safety remains the primary treatment to minimize local progression. Adjuvant radiotherapy should be considered in patients receiving incomplete resection. The long-term clinical outcomes of CN after multimodal treatment seem to be satisfactory.

Case Reports
Safe burr hole surgery for chronic subdural hematoma using dabigatran with idarucizumab.
Chronic subdural hematoma (CSDH) is a common intracranial hematoma. The number of patients who undergo anticoagulant therapy including a direct oral anticoagulant (DOAC) is expected to increase. Recently, idarucizumab, the antidote for dabigatran, which is a DOAC, has been developed. We successfully treated CSDH with dabigatran using emergency burr hole surgery and idarucizumab. ⋯ Dabigatran should be used for atrial fibrillation detected after head trauma. Emergency surgery can be safely performed for CSDH with dabigatran using idarucizumab.

Lumbar puncture (LP) is an essential part of adult neurology residency training. Technologic as well as nontechnologic training is needed. However, current assessment tools mostly focus on the technologic aspects of LP. We propose a training method-problem- and simulator-based learning (PSBL)-in LP residency training to develop overall skills of neurology residents. ⋯ Compared with traditional teaching model, PSBL for LP training can develop overall surgical skills, including technical and nontechnical elements, improving performance. Residents in the PSBL group were more confident and effective in performing LP.

Comparative Study
Microsurgical vs. endovascular treatments for blood-blister aneurysms of the internal carotid artery: a retrospective study of 83 patients in a single center.
Blood-blister aneurysms (BBAs) of the internal carotid artery (ICA) are challenging lesions with high morbidity and mortality. Both surgical and endovascular approaches have been used to treat BBAs; however, little is known about their safety and efficacy. ⋯ BBAs are challenging vascular lesions with poor prognosis. Endovascular treatment may be more effective and safer with better outcomes than surgical approaches.

Spaceflight and the associated gravitational fluctuations may impact various components of the central nervous system. These include changes in intracranial pressure, the spine, and neurocognitive performance. The implications of altered astronaut performance on critical spaceflight missions are potentially significant. The current body of research on this important topic is extremely limited, and a comprehensive review has not been published. Herein, the authors address this notable gap, as well as the role of the neurosurgeon in optimizing potential diagnostic and therapeutic modalities. ⋯ The microgravity environment encountered during spaceflight impacts intracranial physiology. This includes changes in intracranial pressure, the spinal column, and neurocognitive performance. Herein, we present a systematic review of the published literature on this issue. Neurosurgeons should have a key role in the continued study of this important topic, contributing to both diagnostic and therapeutic understanding.
