To report a new index, the spinal cord (SC) line, and a new classification to predict postoperative recovery effect in patients with multilevel cervical spondylotic myelopathy (CSM). ⋯ The SC line and its classifications can predict postoperative recovery in patients with multilevel CSM.

Deep brain stimulation (DBS) may cause various complications including intracerebral hemorrhage (ICH). Because ICH causes devastating neurologic outcomes, various surgical techniques are attempting to reduce the chances of ICH. More importantly, early detection and proper management of postoperative ICH are indispensable. ICH may occur immediately or delayed following DBS; in this study, we analyzed the clinical features of delayed ICH after DBS. ⋯ Our study demonstrates that delayed ICH can occur after DBS even with normal brain CT immediately after DBS. Because ICH can cause serious neurological sequelae, the possibility of delayed ICH after DBS should be considered for the optimal management of patients.

Case Reports
Vertebrobasilar Insufficiency Due to Distal Posterior Inferior Cerebellar Artery Compression in Chiari 1.5.
Chiari malformation is characterized by radiographic evidence of herniation of cerebellar tonsils below the foramen magnum and a symptom complex of headaches; breathing, swallowing, or sleep difficulties; ataxia; restless; and motor and/or sensory deficits. ⋯ In the setting of severe Chiari malformations, particularly the Chiari 1.5 variant, assessment of the posterior fossa vasculature may be useful in defining a subset of patients with preoperative compromise in posterior fossa blood flow and postoperative expectations. Preoperative planning and exploration of midline dorsal brain stem along with the tonsilomedullary fissure could be helpful for contribution of vascular pathology among Chiari symptoms complex in these patients.

Ventriculostomy from Paine's point is an effective technique to ensure that the brain is relaxed for aneurysm surgery. This study aimed to use Paine's point for other neurosurgical procedures (except for those that require a pterional approach) by delineation of surface landmarks for identification of Paine's point on the cranium and scalp. ⋯ By accurate surface marking on skull and skin, the use of Paine's point for ventriculostomy performed via an interhemispheric approach or for simple burr-hole surgery was found to be safe and reliable.

Pure endoscopic resection has become the most popular surgical approach for pituitary adenoma. Intraoperative magnetic resonance imaging (iMRI) systems have been in use for endoscopic resection of pituitary adenomas. This study aimed to evaluate the effectiveness of iMRI and neuroimaging navigation techniques during endoscopic endonasal transsphenoidal surgery of pituitary adenomas. ⋯ The use of iMRI and neuronavigation not only leads to a higher rate of tumor resection but also helps in detecting and removing hematomas in the surgical area. Follow-up examinations of extent of residual tumor at 3 months postoperatively were consistent with intraoperative results. Residual tumor volume in the suprasellar region was usually less than that observed intraoperatively.
