Review Case Reports
Primary seeding of a myxopapillary ependymoma: Is it a different disease in an adult population? Case report and review of the literature.
Myxopapillary ependymoma (MPE) is a slow-growing tumor, occurring most often in adults. It originates from the filum terminale in the area of the conus medullaris and cauda equina and is considered a benign lesion. Despite this classification, however, recurrence after both partial and gross total resection is well known. ⋯ Complete craniospinal magnetic resonance imaging studies should be done before and after surgery in patients who present with a multifocal primary MPE. Furthermore, patients with a history of primary tumor seeding of MPE should be thoroughly evaluated radiologically. Unlike in pediatric populations, the need for postoperative irradiation in adults is less clear and further studies-particularly genetic ones-are warranted.

Randomized Controlled Trial Multicenter Study Comparative Study
A Clinical Comparison of Anterior Cervical Plates versus Stand-Alone Intervertebral Fusion Devices for Single-Level Anterior Cervical Discectomy and Fusion Procedures.
To compare radiologic and clinical outcomes, including rates of dysphagia and dysphonia, using a no-profile stand-alone intervertebral spacer with integrated screw fixation versus an anterior cervical plate and spacer construct for single-level anterior cervical discectomy and fusion (ACDF) procedures. ⋯ Anterior cervical discectomy and fusion with stand-alone spacers resulted in similar clinical and radiologic outcomes as compared with plate and spacers and may help minimize postoperative dysphonia.

Patients with brain tumors are known to have deficits in cognitive, motor, and emotional domains. Comprehensive evaluation of the patient with brain tumor includes taking into account all these domains at baseline and throughout treatment. Standard neuropsychological assessment methods, however, are lengthy, expensive, and often are variable. The authors appraised the feasibility of using a brief, inexpensive, comprehensive, and standardized neuropsychological battery, the National Institutes of Health (NIH) Toolbox, to assess these domains in patients with diffuse glioma. ⋯ The NIH Toolbox represents a feasible alternative to current neuropsychological batteries in the assessment of neurosurgical patients. It can be administered quickly, inexpensively, and will give the neurosurgical community a common currency when reporting neuropsychological results.

Anterior cervical discectomy (ACD) is one of the most common spinal surgeries. Although rare, iatrogenic vertebral artery injuries (VAIs) are potentially life-threatening. Risk factors are anatomic, operative, and pathologic. We report a rare case of iatrogenic VAI during ACD and successful endovascular treatment with no long-term complications. We also review the literature on all VAIs associated with ACD and fusions. Risk factors and the safety and effectiveness of various management modalities are discussed. ⋯ Delayed pseudoaneurysm formation after iatrogenic VAI can occur. Endovascular embolization can be a safe treatment alternative to surgical repair.

Multicenter Study Controlled Clinical Trial
Patients' Preference of the Timed Up and Go (TUG) Test or Patient-Reported Outcome Measures (PROMs) Before and After Surgery for Lumbar Degenerative Disc Disease.
The Timed Up and Go (TUG) test, as a measure of objective functional impairment in lumbar degenerative disk disease (DDD), complements patient-reported outcome measures (PROMs) of subjective functional impairment. ⋯ The TUG test is preferred over a battery of PROMs by 60%-70% of patients with lumbar DDD not only in the preoperative, but also in the postoperative, setting. High functional disability does not result in avoidance of the TUG test, and repeated assessments lead to higher preference.
