Despite advances in treatment of glioblastomas (GBMs), the median survival remains 14-16 months. In the United States, 52.5 million people ≥12 years of age used cannabis in 2021. We aim to elucidate differences in complications after craniotomy for resection of GBM between users and nonusers of cannabis. ⋯ This retrospective population-based study sounds a higher rate of neurologic complications among patients using cannabis who also had a newly diagnosed GBM. This suggests the lack of a protective effect from use of cannabis in patients with primary malignant brain tumors.

In this preliminary study, we investigated the value of fusion techniques by flat detector computed tomography based dual volume rotational angiography (DVRA) for the evaluation of the anatomical relationship of cavernous sinus dural arteriovenous fistula (CSDAVF) and assessed the possibility of transvenous target segment embolization. ⋯ Detailed anatomical information including accurate fistula point, specific feeding arteries, and draining veins could be obtained with various dual volume image fusion techniques. In addition, the target segment embolization of CSDAVF could be possible with understanding of the precise CSDAVF architectures.

Endoscopic pituitary adenoma surgery has a steep learning curve, with varying surgical techniques and outcomes across centers. In other surgeries, superior performance is linked with superior surgical outcomes. This study aimed to explore the prediction of patient-specific outcomes using surgical video analysis in pituitary surgery. ⋯ Superior surgical skill and shorter surgical time were associated with superior surgical outcomes, at a generic and phase-specific level. Such video-based analysis has promise for integration into data-driven training and service improvement initiatives.

Case Reports
Vertical "Half-and-Half" Syndrome with Ipsilateral Pseudoabducens Palsy due to Rostral Midbrain Lacunar Infarction.
Vertical "half-and-half" syndrome, characterized by contralateral upward and ipsilateral downward gaze palsy, is a rare variant of vertical eye movement disturbance. Similarly, pseudoabducens palsy, manifesting as abductive palsy despite no lesion to the pons, constitutes another rare type of eye movement disturbance. ⋯ We present a rare case report detailing a patient exhibiting vertical "half-and-half" syndrome with ipsilateral pseudoabducens palsy following a left lacunar infarction of the thalamo-mesencephalic junction. Additionally, we discuss the potential underlying mechanisms contributing to this rare combination of eye movement disorders.

Middle meningeal artery (MMA) embolization for the treatment of chronic subdural hematomas (cSDHs) is becoming increasingly prevalent. It is essential to optimize the safety and cost effectiveness of the postprocedural management. In this study, we examined our cases over time to determine the most appropriate postprocedural destination. ⋯ MMA embolization for cSDH is a safe procedure with low rate of procedure-related complications. In carefully selected patients, the necessity ICU admission postoperatively should be weighed against better hospital resource utilization.
