Glioblastoma multiforme (GBM) is an aggressive primary brain tumor with dismal survival. This study aims to examine the prognostic value of primary tumor sites and race on survival outcomes. ⋯ Black racial background and temporal, occipital, or parietal primary tumor sites are suggestive of positive survival outcomes. Conversely, white racial background with primary tumor sites in the brain overlapping and NOS areas seem to be associated with negative outcomes and decreased survival. Thus, racial background and primary tumor site may be useful prognostic factors in patients with GBM.

Numerous scores have been developed for prognostication of outcomes in intracerebral hemorrhage (ICH). Prediction models must be validated internally and externally before they are considered widely applicable. We aim to independently externally validate and compare 3 prediction models (ICH score, ICH grading scale [ICH-GS], and simplified ICH [sICH]) in our population, which has not been previously done. ⋯ This study successfully independently validates the ICH score, ICH-GS, and sICH score in a large patient cohort with spontaneous ICH, which has not been previously done in this non-Western population. We recommend the use of the ICH-GS as a prognostication tool in our patients instead of the widely used ICH score.

We report the availability of a newly developed, malleable, tin-alloyed omnidirectional retractor-supporting (OD) ring for steady and safe ventriculoperitoneal (VP) shunt laparotomy. ⋯ Our newly developed retraction system with a malleable, tin-alloyed OD ring and minihooks may allow safe and steady small laparotomy for VP shunt.

Meningiomas of the clinoid region pose a formidable surgical challenge. Pterional craniotomy is the traditional approach and is often associated with high-risk postsurgical morbidities. In the current presentation, we describe an elderly male with a clinoidal meningioma who underwent a minimally invasive supraorbital craniotomy for tumor resection. ⋯ Initial intraoperative steps include dissection via the corridor between the carotid artery and the tentorium, as well as exposing the tumor in the opticocarotid triangle, followed by tumor dissection using microsurgical techniques. Care must be taken to preserve the supraorbital nerve to prevent frontal numbness and avoid violation of the frontal sinus to prevent postoperative cerebrospinal fluid leak. Emphasis on using this minimally invasive procedure for clinoidal meningiomas over the pterional approach for a select cohort of patients is laid, considering the cosmetic merits and adequate extent of tumor resection.

Recognition of transdural spinal cord herniation has increased over the past decade. This condition remains little known, particularly outside the specialized fields of spinal surgery and neuroradiology, leading to a significant delay in clinical diagnosis and treatment. ⋯ We describe our surgical experience to untether the spinal cord by wrapping a dura graft around the spinal cord. Three case reports and a review of the literature are discussed.
