Idiopathic spinal cord herniation is a rare condition that involves spinal cord herniation through a defect in the ventral dura. ⋯ Idiopathic spinal cord herniation is an uncommon spinal cord disorder with a paucity of data reported. Our case report of a classic case of idiopathic spinal cord herniation presenting as Brown-Sequard syndrome and managed surgically will contribute to the data in this field.

Primary central nervous system (pCNS) melanoma is an extremely rare malignant tumor. We explored the incidence, outcomes, and predictors of pCNS melanoma. ⋯ The overall age-adjusted incidence rate of pCNS melanoma is 0.52 per 10,000,000 person-years. Age ≤19 years and intracranial tumor location are independent risk factors of low survival rate, whereas gross total resection is associated with better survival rate.

Thyroid cancer, one of the most common endocrine malignancies in developed areas and China, is associated with favorable prognosis. However, the presence of spinal metastases will remarkably reduce the life expectancy for patients with thyroid cancer. In addition, limited information is available about such disease. ⋯ Findings in this study indicate that age of ≤50 years, single segment involved, and follicular thyroid cancer are favorable prognostic factors for patients with thyroid cancer spinal metastases.

The aims of this study were to evaluate the risk factors for muscle injury in patients undergoing posterior lumbar spinal surgery and the clearance of postoperative biochemical changes following lumbar fusion and secondarily to evaluate the timing for monitoring postoperative biochemical serum levels and potential clinical correlation. ⋯ The risk of RML increases with prolonged and invasive surgery with higher bleeding potential. Knowing the clearance of postoperative biochemical changes permits a standardized strategy with measurements in precise intervals, thereby avoiding unnecessary costs. The clinical significance is still undetermined.

Perimesencephalic nonaneurysmal subarachnoid hemorrhage (PNSAH) is a well-described subset of subarachnoid hemorrhage with an excellent prognosis in adults. However, its characteristics in the pediatric population have not yet been fully understood. We present a case of acute hydrocephalus requiring external ventricular drainage following pediatric PNSAH. ⋯ We propose that acute hydrocephalus be suspected in pediatric patients with nonaneurysmal subarachnoid hemorrhage filling all perimesencephalic cisterns, as in adults. We also propose that one of the possible causes of pediatric PNSAH as of venous origin and related to the abnormal drainage pattern of basal vein of Rosenthal and elevation of venous pressure with exercise. Immediate surgical drainage could obtain a good outcome in a symptomatic case.
