Management of intracranial chondromas (ICDs) is difficult. This study aims to propose a tailored management strategy based on our management of ICDs. ⋯ The therapeutic strategy for ICDs should be individualized and should consider preoperative variables. Gross total resection was attempted if the tumors were resectable; otherwise, subtotal resection was an alternative. In patients with partial resection and evident atypia/mitotic activity, consultation with an oncologist for radiotherapy was recommended.

Selection of the access myelotomy is a key issue in surgery for spinal intramedullary tumors. This study focused on surgical outcomes with the posterolateral sulcus (PLS) approach, equivalent to dorsal root entry zone myelotomy. ⋯ These findings suggest that the PLS approach can provide direct access to tumors with minimal tissue damage, when applied appropriately after careful case selection.

Review Case Reports
Treating CSF Rhinorrhea without Dura Repair - A Case Report of Posterior Fossa Choroid Plexus Papilloma.
Choroid plexus papilloma revealed by nontraumatic cerebrospinal fluid (CSF) rhinorrhea has only been described 5 times, to our knowledge, in the literature. The challenges in this situation are to recognize CSF leak, to rapidly understand the pathophysiology of the leak, and to choose the best treatment strategy in emergency. We report an original case of posterior fossa choroid plexus papilloma revealed by CSF leak. We then discuss the surgical strategy and the pathophysiology of CSF leak, which is explained, in this case, by both hyperproduction of CSF and local skull base erosion. ⋯ Our case shows that 1) causal reasoning is of major importance when dealing with CSF rhinorrhea and that 2) dura repair can be avoided when treating CSF leak secondary to posterior fossa choroid plexus papilloma.

Comparative Study
A Retrospective Study of Thoracolumbar Fractures Treated with Fixation and Non-fusion Surgery of Intra-vertebral Bone Graft Assisted with Balloon Kyphoplasty.
Posterior fixation and fusion is the primary treatment for thoracolumbar fractures, although this treatment may sacrifice range of motion (ROM) to achieve stability, rather than treating the fracture itself. Two issues addressed when treating thoracolumbar fractures are 1) replacing the fractured vertebrae, especially the upper end plate of the injured vertebrae and 2) providing strong fixation with biomechanical stability and flexibility. ⋯ Nonfusion treatment of intravertebral bone graft assisted with balloon kyphoplasty showed good fracture reduction, deformity correction, fracture healing, and ROM maintenance. There were no complications associated with the implant.

Non-small-cell lung cancer (NSCLC) is one of the most common primary tumor sites among patients with metastatic spinal cord compression (MSCC). This disorder is related to neurologic dysfunction and can reduce the quality of life, but the association between MSCC and death is unclear. The aim of this study was to analyze the impact of the occurrence of symptomatic MSCC on overall survival of patients with NSCLC. ⋯ MSCC is an important and independent predictor of NSCLC worse survival. This effect was not influenced by sociodemographic and clinical factors.
