Only a few case reports and case series exist reporting on primary chondrosarcomas of the spine. The objective of this study was to gain a better understanding of this patient population and surgical techniques used for treatment. ⋯ CS is a rare lesion that most commonly presents in adult male patients. En bloc surgical resection was associated with a significant decrease in recurrence, mortality, and increased survival compared with the other surgical techniques. In addition, any surgical technique that involved entering the tumor capsule showed a significantly greater risk for recurrence and death.

To present the basic topographic and anatomic features of the clivus and adjacent structures with an objective of possible improvements and optimization of the extended endoscopic endonasal posterior (transclival) approach when removing tumors of the clivus and anterior regions of the posterior cranial fossa. ⋯ The endoscopic endonasal transclival approach can be used to obtain access to centrally located tumors of the posterior cranial fossa. It is an alternative to transcranial approaches in the surgical treatment of tumors of the clivus.

Implantation of deep brain stimulation (DBS) electrodes requires stereotactic imaging. Stereotactic magnetic resonance imaging (MRI) for DBS surgery has become more popular and intraoperative MRI scanners have become more available. We report on our cohort of movement disorder patients who underwent intraoperative stereotactic MRI-only DBS electrode implantation. ⋯ Intraoperative stereotactic MRI for DBS surgery is feasible with high stereotactic accuracy and low rates of complication.

Superficial siderosis of the central nervous system is a rare neurologic disorder characterized by the superficial deposition of hemosiderin in the subpial layer resulting in iron-related progressive neurodegeneration. ⋯ The patient was successfully treated with T6-T8 transpedicular partial corpectomy, as well as diskectomy with decompression followed by watertight closure of the CSF leak. Intraoperative watertight closure of the CSF leak was achieved.
