Well-defined risk factors for the identification of patients with meningioma who might benefit from preoperative or early postoperative seizure prophylaxis are unknown. We investigated and quantified risk factors to determine individual risks of seizure occurrence in patients with meningioma. ⋯ Seizure prophylaxis might be considered for patients at high risk of developing seizures who are for other reasons being considered for watchful waiting instead of resection. In contrast, our data do not provide any evidence of the efficacy of perioperative AEDs in patients with meningioma.

Vision is important for patients with hearing loss caused by neurofibromatosis type 2 (NF2). Tumors adjacent to the anterior visual pathway can potentially impair the vision. Only a few case reports and small-series studies have been reported. ⋯ Tumors adjacent to the anterior visual pathway, although uncommon in patients with NF2, can cause progressive visual loss. Early surgical intervention seems to be the primary treatment strategy, except for in patients' optic nerve sheath meningiomas. If patients adopt a wait and see policy, regular visual examination seems to be mandatory.

This study aimed to assess any correlation between serum levels of homocysteine (Hcy) and markers of cerebral hemodynamics, endothelial dysfunction, and cognition impairment in patients with traumatic brain injury (TBI). ⋯ Hcy has a significant correlation with markers of cerebrovascular, endothelial, and cognition abnormality in TBI patients.

Traumatic Frontal Epidural Hematoma Caused by Multiple Arterial Injuries in the Anterior Fossa.
This case report illustrates the need to evaluate the possibility of multiple arterial sources when presented with a frontal epidural hematoma associated with facial trauma. ⋯ We report a case of an epidural hematoma caused by 2 distinct arterial feeders. We discuss radiologic review and operative management of anterior fossa epidural hematomas and stress the importance of considering arterial bleeding from sources other than the middle meningeal artery in anterior fossa epidural hematomas. We discuss the utility of preoperative angiography for these patients and reinforce the need for acute postoperative imaging to ensure successful operative and patient outcomes.

The current standard treatment protocol for patients with newly diagnosed glioblastoma (GBM) includes surgery, radiotherapy, and concomitant and adjuvant temozolomide (TMZ). We hypothesized that the permeability surface area product (PS) from a perfusion computed tomography (PCT) study is associated with sensitivity to TMZ. The aim of this study was to determine whether PS values were correlated with prognosis of GBM patients who received the standard treatment protocol. ⋯ PSmax from PCT study can help predict survival time in patients with GBM receiving the standard treatment protocol. Survival may be related to sensitivity to TMZ.
