Secretory meningioma (SM) is a rare subtype of World Health Organization (WHO) grade 1 meningioma, associated with significant peritumoral brain edema (PTBE). Because of this, SM may be mistaken preoperatively to be a WHO grade 2 meningioma (G2M). In this study, we identified radiographic features to differentiate these 2 tumor types preoperatively to help inform surgical decision-making. ⋯ In this study, we found that preoperative FLAIR hyperintensity, severe PTBE, and higher nADC values correlated with SM pathology, and larger size and cystic component were associated with G2M. Accurate identification of SM on preoperative imaging may provide surgeons useful information in decision-making.

We sought to observe the effectiveness and safety of multimode mechanical thrombectomy in the treatment of acute ischemic stroke. ⋯ Multimode mechanical thrombectomy is a safe and effective therapy for the intracranial occlusion of large vessels in patients with acute ischemic stroke.

The objective of this study was to investigate the incidence and risk factors of rod fractures (RFs) after a single-level lumbar pedicle subtraction osteotomy (PSO) using a side-tightening (ST) pedicle screw system. ⋯ The incidence of RF after a single-level lumbar PSO using the ST pedicle screw system was 12.3% in our cohort. The absence of an adjacent interbody cage was a significant risk factor for RF.

To share our clinical experience of 25 years and identify prognostic factors for progression-free and overall survival in pediatric intracranial ependymomas. ⋯ This single center experience of 25 years confirms the beneficial effect of gross total resection on disease progression. Although spinal seeding seems to affect survival rates, greater number of cases are needed to reveal its full effect.

Surgery for chronic subdural hematoma is one of the most frequent operations in neurosurgical practice. Chronic subdural hematoma mostly afflicts the elderly population. In 2018, Kwon and co-workers, published the Kwon scoring system (KSS), whereby 6 clinical and radiological factors are used to facilitate, and promote quality in, surgical decision-making and counseling of relatives. The aim of this study is to validate the KSS. ⋯ In our material, the KSS did not predict outcome precisely enough to base treatment decisions or counseling of relatives on the scores obtained.
