The aftermath of the Affordable Care Act (ACA) witnessed the rise of narrow networks, which feature fewer providers in exchange for lower premiums. Debate still continues on whether narrow networks provide adequate access to health care, especially in specialty care services such as neurosurgery. The objective of this article was to analyze the 2019 Marketplace plans' impact on delivering outpatient neurosurgical care in New Jersey. ⋯ In more densely populated states such as New Jersey, the impact of narrow networks on neurosurgical coverage is less apparent. However, frustrations regarding access to care still exist because nearly 25% of neurosurgeons do not participate in the standard ACA insurance product. Furthermore, guidelines that define network adequacy in neurosurgery remain elusive, which calls for more robust parameters to monitor and ensure adequate access to health care.

Global neurosurgery encompasses the social and surgical practices that effect the neurologic health of vulnerable and underserved populations in domestic and international resource-limited settings. Formal academic engagement in global neurosurgery is limited in residency programs. Here we explore the current status of global neurosurgery education in residency programs across the United States. ⋯ Formal global neurosurgery training is limited within US residency programs. With rising trends in the neurosurgical disease burden globally, it may benefit residency programs to develop training paths to equip the next generation of neurosurgeons to address such needs.

Clear cell meningioma (CCM) is a rare histologic variant, accounting for only 0.2%-0.8% of all meningiomas. Given their relative infrequency, few cases have been reported. We have presented one of the largest series of patients with intracranial CCM and reported the treatments and outcomes of these patients. ⋯ The data from the present series of 35 patients with CCM have shown distinct contrasts to previous series, with an older mean age and a nearly 1:1 male/female ratio. Although gross total resection and adjuvant postoperative radiotherapy were both independently associated with longer progression-free survival for patients with CCM, tumor recurrence has remained a challenge in the treatment of these patients.

Defect in internal elastic lamina, defect in tunica media, and the amount of collagen and elastin play a role in vessel wall weakening leading to aneurysm formation. A similar picture may be found in connective tissue disorders, such as Marfan syndrome, Ehlers-Danlos syndrome (EDS), neurofibromatosis type 1, and Loeys-Dietz syndrome (LDS), where there is a predominant disorder of collagen formation/maturation. ⋯ The histologic changes seen in skin and the STA in cases of IAs signify a weak connective tissue. Some of these findings are also seen in known connective tissue disorders such as Marfan syndrome, EDS, neurofibromatosis type 1, and LDS. The connective tissue abnormalities found in patients with IAs may be congenital, which gets further accentuated by known risk factors leading to weak vessel wall and subsequent aneurysm formation.

Ependymomas are the most common adult intramedullary spinal tumors.1 Although uncommon in the brainstem, ependymomas make up a large proportion of tumors of this location.2-8 We present an operative video case report of an intrinsic ependymoma at the cervicomedullary junction. The purpose of this report is to present the clinical picture, operative setup, and surgical technique involved in resection of an intramedullary tumor of this region. For best outcome for intramedullary ependymomas, the goal should be gross total resection.1,9,10 These tumors have a relatively distinct plane between tumor and normal parenchyma, making a gross total resection more probable than cases of infiltrative intramedullary astrocytomas.11 Despite this, significant morbidity can be associated with treatment.1 Proper microsurgical technique with use of operative adjuncts can maximize resection while minimizing neurologic injury to optimize outcomes in patients. ⋯ Postoperative magnetic resonance imaging revealed a small amount of residual. He underwent full craniospinal proton beam therapy with boost to the residual and metastases with good outcome. Patient provided consent for this report.
