Andexanet alfa, a novel anticoagulation reversal agent for factor Xa inhibitors, was recently approved. Traumatic intracranial hemorrhage presents a prime target for this drug. The Novel Antidote to the Anticoagulation Effects of Factor Xa Inhibitors study established the efficacy of andexanet alfa in reversing factor Xa inhibitors. However, the association between anticoagulation reversal and traumatic intracranial hemorrhage progression is not well understood. The objective of this study was to determine progression rates of patients with traumatic intracranial hemorrhage on factor Xa inhibitors prior to hospitalization who were managed without the use of andexanet alfa. ⋯ Our results indicate that patients on factor Xa inhibitors with complicated mild TBI have a similar intracranial hemorrhage progression rate to patients who are not anticoagulated or anticoagulated with a reversible agent. The hemostatic outcomes in our cohort were similar to those reported after andexanet alfa administration.

Neuroendoscopy offers wide and close surgical views with fine illumination, even in deep surgical sites. Furthermore, transcylinder surgery has the advantage that a tubular retractor can protect critical neurovascular structures in the surgical corridor. These advantages of neuroendoscopy and transcylinder surgery can contribute to safer and less invasive surgical approaches for deep-seated fourth ventricular lesions, for which various critical neurovascular structures exist along the surgical route. ⋯ Our novel approach can be an effective surgical option for fourth ventricular lesions with minimal cerebellar retraction and injury.

Discharge disposition is an important outcome for neurosurgeons to consider in the context of high-quality, value-based care. There has been limited research into how the unique anatomic considerations associated with parasagittal/parafalcine meningioma resection may influence discharge disposition. We investigated the effects of various predictors on discharge disposition within a cohort of patients with parasagittal/parafalcine meningioma. ⋯ In our single-institution experience, neither extent of SSS invasion nor location along the SSS predicted nonroutine discharge, suggesting that tumor invasion and posterior location along the SSS are not necessarily contraindications to surgery. Our results also highlight the importance of frailty and tumor size in stratifying patients at risk of nonroutine discharge disposition.

Case Reports
Infantile giant intracranial aneurysm resection and in situ anastomosis: A case report.
Infantile intracranial aneurysms (IAs) are extremely rare. IA clipping and embolization have been the most common treatment options. Infantile giant IAs treated by surgical resection and in situ anastomosis have rarely been reported. ⋯ Infantile giant IAs are extremely rare. Chronic inflammation might be involved in the pathogenesis of infantile dissecting IAs. IA resection and in situ anastomosis could be a reasonable choice in the management of infantile giant IAs that cannot be completely clipped or embolized.

Chondroblastoma is an uncommon benign neoplasm of cartilaginous origin usually involving the long bones. The temporal bone is a rare location for this tumor. The clinical profile, optimal medical and surgical management, and outcomes of treatment for temporal bone chondroblastoma remain unknown. ⋯ Temporal bone chondroblastoma has a distinct clinical profile from chondroblastoma of long bones. Surgery is the mainstay of treatment, and radiation therapy may be given after subtotal excision. Outcomes are generally favorable after treatment.
