Numerous scientists and researchers have been developing advanced procedures and methods for diagnosing the kind and phase of a human tumor. Brain tumors, which are neoplastic and abnormal developments of brain cells, are one of the most prominent causes of death. Brain tumors, also known as lesions or neoplasia, may be roughly classified as either primary or metastatic. Primary brain tumors arise from brain tissue and its surrounding environment. The recognition of brain tumors using magnetic resonance images via a deep learning technique such as convolutional neural network (CNN) has garnered significant academic interest over the last few decades. ⋯ In conclusion, we suggest that one of the next paths of study will be the incorporation of other databases to advance CNN-based brain tumor identification from magnetic resonance images. No drug dosages are applied in this work.

Cerebral cavernous malformations (CCMs) or cavernomas, are low-flow sinusoidal vascular anomalies of the central nervous system comprised of capillary networks filled with blood in various stages of thrombosis. This bibliometric analysis summarizes the most-cited articles on CCM and highlights the contributing articles to today's evidence-based practice. ⋯ The bibliometric analysis provides a quantitative overview of how medical topics and interventions are analyzed in academic medicine. In the present study, we evaluated the global trends in CCMs by analyzing the top 100 most cited papers.

Multicenter Study
A Novel Stereotactic Aspiration Technique for Intracerebral Hemorrhage.
Minimally invasive surgery is effective and recommended for treatment of intracerebral hemorrhage; however, neurosurgeons in grass-root hospitals in underdeveloped countries lack effective and precise minimally invasive surgery techniques. The aim of this study was to present a technique of computed tomography angiography-based three-dimensional-printed navigation mold-guided stereotactic aspiration and demonstrate its clinical application using a hard needle in a series of patients. ⋯ Our novel method of stereotactic aspiration benefited patients in this study with good percent clot removal, few surgery-related complications, and a favorable prognosis. Manual segmentation with 3D Slicer could be used to provide the neurosurgeon with dependable information about hematoma volume. This cheap and convenient technique may be applied in grass-root hospitals in underdeveloped countries. Assessment in multicenter prospective clinical trials is needed.

The role of hemorrhage volume in risk of vasospasm, delayed cerebral ischemia (DCI), and poor outcomes after aneurysmal subarachnoid hemorrhage (SAH) is well established. However, the relative contribution of blood within individual compartments is unclear. We present an automated technique for measuring not only total but also volumes of blood in each major compartment after SAH. ⋯ An automated imaging algorithm can measure the volume of bleeding after SAH within individual compartments, demonstrating cisternal plus sulcal (and not ventricular) blood contributes to risk of DCI/vasospasm. Automated blood volume was independently associated with outcome, while qualitative grading was not.

There is ongoing discussion on pros and cons in terms of different anesthesia protocols for awake craniotomy (AC) with direct brain stimulation. The aim of this study is to share our anesthesia protocol and present our patients' perspectives. ⋯ AC using the monitored anesthesia care protocol was a safe and well-tolerated procedure with satisfactory patient experience. Extensive preoperative preparation should be considered a key part of the procedure.
