This study aimed to characterize pyramidal tract shift in different regions of the brain during glioma resection and its association with head position and tumor location. ⋯ Direction of pyramidal tract shift in 3 dimensions is unpredictable; hence shift radius is a more clinical useful concept. Shift radius was largest above the ventricles and was strongly influenced by head position, with a trend for temporal lobe tumors to exhibit larger shifts.

Intraoperative monitoring of cerebral microcirculation in patients with subarachnoid hemorrhage (SAH) may predict the postoperative neurologic outcome. In this pilot study, we examined the value of a novel noninvasive real-time measurement technique for detecting changes in local microcirculation. ⋯ Our results indicate the potential benefit of intraoperative combined laser-Doppler flowmetry and spectrophotometry for predicting postoperative clinical outcomes in this small patient sample. Larger-cohort testing is needed to verify our findings and show the possible merits of this novel method.

Gamma Knife radiosurgery (GKS) for the treatment of vestibular schwannoma (VS) introduces risks to the facial nerve and auditory perception and may involve post-treatment complications such as pseudoprogression, hydrocephalus, and other cranial neuropathies. This study of patients with VS who underwent GKS investigated radiosurgical results, focusing on post-treatment complications and identifying the factors that predict such complications. ⋯ Further prospective studies should be designed to provide further insight into the exact relationship between the predictive factors we investigated and post-treatment complications.

Guidewire Breakage During Cavernous Sinus Sampling: A Rare Complication and Its Treatment.
Venous sampling methods are valuable tools for the diagnosis of pituitary adenomas. However, these interventions also have complications, which may complicate the treatment process. ⋯ Current surgical experience on endoscopic skull base surgery allows management of diagnostic complications related to the cavernous sinus, such as safe access to materials which were inadvertently left during CSS, without the necessity for further interventions.

Cranium bifidum occultum is a disorder of skull ossification presenting as an enlarged posterior fontanelle in the upper posterior angle of the parietal bone near the intersection of the sagittal and lambdoid sutures. The standard treatment for cranium bifidum occultum is observation. ⋯ The patient underwent posterior vault reconstruction for correction of cranium bifidum occultum defect followed by bifrontal craniotomy and orbital box osteotomies for correction of orbital hypertelorism and nasal deformity. To our knowledge, this is the first reported case describing surgical treatment for cranium bifidum occultum associated with orbital hypertelorism.
