Sphenoid wing meningiomas are the third most common group of intracranial meningiomas. Their management is a challenge because of their bone invasion potential and their proximity to neurovascular structures and the cavernous sinus. ⋯ Sphenoid wing meningioma is a large group with characteristics associated with skull base meningiomas and convexity meningiomas. The results of surgery and other adjuvant treatments are heterogeneous.

Review Meta Analysis
The reliability of fMRI in brain tumor patients: a critical review and meta-analysis.
Formal studies that validated functional magnetic resonance imaging (fMRI) against direct cortical stimulation (DCS) have shown inconsistencies. ⋯ The results from the present analysis of the available reported evidence suggest that fMRI itself (due to neurovascular uncoupling) or analysis of the findings have limitations regarding reliability when validated against DCS. From the existing studies, our results indicate that using fMRI alone for surgical planning could lead to undesirable outcomes.

We sought to explore whether additional bone grafting of the atlantoaxial joint increases the bone fusion rate of iliac crest autograft in posterior occipitocervical fusion surgery. ⋯ Additional bone grafting of the atlantoaxial joint could increase the bone fusion rate of iliac crest autograft in posterior occipitocervical fusion.

Case Reports
Neonatal Hyponatremia in the Setting of Untreated Progressive Hydrocephalus: Case Report.
Hyponatremia in the neonatal population is an uncommon occurrence and can be associated with significant increase in morbidity and mortality. In the neonatal population, it is typically associated with an excess of antidiuretic hormone and rarely has been found to be associated with hydrocephalus, short of being caused by the subsequent treatment of hydrocephalus. ⋯ Hydrocephalus secondary to intraventricular hemorrhage is a notable complication in the premature neonatal population. Physicians should be aware of its potential association with hyponatremia and consider early neurosurgical intervention when other etiologies of the electrolyte disturbance cannot be identified.

To compare the clinical accuracy and perioperative outcomes for pedicle screw placement in transforaminal lumbar interbody fusion (TLIF) between the robot-assisted (RA) technique and fluoroscopy-guided (FG) technique. ⋯ RA pedicle screw placement is an accurate and safe procedure in TLIF for lumbar degenerative disease.
