Journal of Neurosurgery, Ahead of Print. OBJECTIVEA surgical series of 201 benign and malignant peripheral nerve sheath tumors (PNSTs) was assessed to characterize the anatomical and clinical presentation of tumors and identify predictors of neurological outcome, recurrence, and extent of resection.METHODSAll surgically treated PNSTs from the Division of Neurosurgery at Toronto Western Hospital from 1993 to 2010 were reviewed retrospectively.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVECarotid artery stenting (CAS) has been considered to prevent ischemic strokes caused by stenosis of the cervical carotid artery. The most common complication of CAS is new cerebral infarction. The authors have previously reported that the jellyfish sign—the rise and fall of the mobile component of the carotid plaque surface detected by carotid ultrasonography—suggests thinning and rupture of the fibrous cap over the unstable plaque content, such as the lipid-rich necrotic core or internal plaque hemorrhage.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEReports on supratentorial extraventricular ependymoma (STE) are relatively rare. The object of this study was to analyze the clinical, radiological, and histological features and treatment outcomes of 14 patients with STE.METHODSOverall, 227 patients with ependymoma underwent surgical treatment in the authors’ department between January 2010 and June 2015; 14 of these patients had STE.… Read More...

Journal of Neurosurgery, Ahead of Print. Brainstem cavernous malformations (CMs) pose significant challenges to neurosurgeons because of their deep locations and high surgical risks. Most patients with brainstem CMs present with sudden-onset cranial nerve deficits or ataxia, but uncommonly patients can present in extremis from an acute hemorrhage, requiring surgical intervention.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEBypass surgery is the most common treatment for moyamoya disease (MMD), but there is controversy over which surgical modality is best. The objective of this study was to evaluate the clinical outcome of patients with MMD after undergoing different surgical modalities.METHODSA series of 696 consecutive MMD patients treated between June 2009 and May 2015 were screened in this prospective cohort study.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVESkull base chondrosarcoma is one of the most intractable tumors because of its aggressive biological behavior and involvement of the internal carotid artery and cranial nerves (CNs). One of the most accepted treatment strategies for skull base chondrosarcoma has been surgical removal of the tumor in conjunction with proactive extensive radiation therapy (RT) to the original tumor bed.… Read More...

Journal of Neurosurgery, Ahead of Print. OBJECTIVEExome sequencing studies have recently demonstrated that papillary craniopharyngiomas (PCPs) and adamantinomatous craniopharyngiomas (ACPs) have distinct genetic origins, each primarily driven by mutually exclusive alterations: either BRAF (V600E), observed in 95% of PCPs, or CTNNB1, observed in 75%–96% of ACPs.… Read More...

Journal of Neurosurgery: Spine, Ahead of Print. OBJECTIVEThe goal of this study was to characterize the long-term clinical and radiological results of articular segmental decompression surgery using endoscopy (cervical microendoscopic laminotomy [CMEL]) for cervical spondylotic myelopathy (CSM) and to compare outcomes to conventional expansive laminoplasty (ELAP).METHODSConsecutive patients with CSM who required surgical treatment were enrolled.… Read More...
