BACKGROUND The incidence (e.g., 3-27%) and the types of cerebrospinal fluid (CSF) fistulas occurring during multilevel lumbar laminectomy with noninstrumented spinal fusions varies. METHODS From 2000 to 2015, we retrospectively evaluated the incidence/etiologies of CSF fistulas occurring for 336 patients undergoing average 4.7 laminectomies with average 1.4 level noninstrumented fusions over ...

An ectopic cerebellum, as in Chiari malformations and ectopic cerebellar dysplastic tissue, is a common finding; however, the presence of an organized ectopic cerebellum is exceedingly rare. We describe the MR imaging, surgical, and histologic appearance of an intraspinal ectopic cerebellum in an infant.

Intramedullary tumours arise within the substance of the spinal cord, whereas extramedullary tumours are extrinsic to the cord. About two thirds of spinal cord tumors in adults are extramedullary in location, among which nerve sheath tumors, meningiomas and Filum terminale ependymomas account for the most. Metastatic...
