Review Comparative Study
Comparison of Multilevel Cervical Disc Replacement and Multilevel Anterior Discectomy and Fusion: A Systematic Review of Biomechanical and Clinical Evidence.
The aim of this study was to comprehensively compare the clinical and biomechanical efficiency of anterior cervical discectomy and fusion (ACDF) with anterior cervical disc replacement (ACDR) for treatment of multilevel cervical disc disease using a meta-analysis and systematical review. ⋯ Multilevel ACDR may be an effective and safe alternative to ACDF in terms of clinical and biomechanical performance. However, further multicenter and prospective studies should be conducted to obtain a stronger and more reliable conclusion.

Magnetic Resonance Imaging Features in Solitary Cerebral Langerhans Cell Histiocytosis: Case Report and Review of Literature.
In this study, we report a case of solitary Langerhans cell histiocytosis (LCH) without skull or systemic lesions including reviewing the initial magnetic resonance (MR) findings of cerebral LCH. ⋯ In conclusion, additional sulcal enhancement around the mass lesion might be a clue MR imaging feature of intracerebral LCH, and special MR imaging techniques such as perfusion imaging, diffusion-weighted imaging, and MR spectroscopy could be helpful in differential diagnosis.

Surgical Treatment for Odontoid Fractures in Patients with Long-Standing Ankylosing Spondylitis: A Report of 3 Cases and Review of the Literature.
Ankylosing spondylitis (AS) is classified as a chronic inflammatory seronegative rheumatic arthritis. Patients with AS are more likely to sustain a fracture of the cervical spine compared with the general population. Most fractures occur in the lower cervical spine and manifest at the level of the intervertebral disc. There have been few reports about the surgical treatment for upper cervical spine fractures in patients with AS, especially odontoid fractures. We present 3 cases of odontoid fracture in patients with long-standing AS. ⋯ Odontoid fracture with atlantoaxial dislocation in patients with long-standing AS is uncommon. Clinicians must be cautious in assessing such patients with any episode of trauma. Computed tomography and magnetic resonance imaging can be helpful in demonstrating occult odontoid fractures. Posterior occipitocervical fusion with internal fixation may benefit these patients, although at the cost of sacrificing the last motion segment.

Review Case Reports
Giant Cell Ependymoma of Cervicomedullary Junction: A Case Report of a Long-Term Survivor and Literature Review.
Ependymoma accounts for 3%-9% of all neuroepithelial tumors. Giant cell ependymoma (GCE) is a rare and distinct variant, with only 22 cases described in the literature. The 2007 World Health Organization classification first acknowledged this rare subtype. The cytologic features of GCE include the presence of pleomorphic giant cells with several cellular atypias, which at intraoperative frozen diagnosis may appear to be high-grade glial lesions. Despite its apparently malignant histology, GCE seems to be a neoplasm with a relatively good prognosis. Extended tumor removal is the gold standard without adjuvant treatment. ⋯ As the intraoperative diagnosis can be misleading, whenever a cleavage plane is recognized, it is essential to perform a gross total resection with the aid of intraoperative neurophysiologic monitoring, to improve prognosis and neurologic outcome. Data reported in the literature show that prognosis is mainly influenced by grade of resection.

Review Case Reports
Primary Intracranial Rhabdomyosarcoma in the Cerebellopontine Angle Resected After Preoperative Embolization.
Primary intracranial rhabdomyosarcoma is a very rare malignant tumor. Owing to moderately vascular and firm characteristics of the tumor, complete removal without complications is often difficult. In pediatric patients, the volume of total blood is less than in adults, and minimal intraoperative hemorrhage is desirable. ⋯ Successfully resection of primary intracranial rhabdomyosarcoma was achieved after preoperative embolization. Tumor vascularity was significantly reduced, and gross total removal was achieved safely with less hemorrhage.
