The fornix is a region of greatest neurosurgical interest in regards to its complex anatomy and surgical approaches to this area. The objective of this study was to evaluate the morphology of the triangular recess (TR) and its role in the growth pattern of the colloid cysts (CC) within the third ventricle and in the choice of the surgical approach for their removal. Furthermore, to compare the results of the dissections with measurements performed on a magnetic resonance imaging scan. ⋯ The anatomy of the TR influences the growth pattern of CC within the ventricular cavity and determines the surgical strategy for their removal.

To describe the operative methods and to investigate the efficacy of ventral neural decompression under microscopic vision with oblique lumbar interbody fusion (OLIF). ⋯ Microscopic ventral neural decompression with OLIF could achieve satisfactory clinical results with minimal complications in selected patients with extruded or sequestered disk.

The aim of this study was to evaluate the safety and efficacy of Gamma Knife radiosurgery (GKRS) in patients with multiple intracranial meningiomas (MIMs). ⋯ GKRS is a safe and effective treatment for MIMs. Variables including surgical resection before GKRS more than once, high grade WHO classification, peritumor edema, and >2 tumors treated by GKRS are predictors of unfavorable outcome after GKRS.

Tumor-to-tumor metastasis of hepatocellular carcinoma to a vestibular schwannoma: case report.
Intracranial metastasis is a common complication of systemic malignancy. A rare subset of intracranial masses constitutes tumor-to-tumor metastasis, in which an extracranial neoplasm hematogenously spreads to an existing intracranial lesion. ⋯ Tumor-to-tumor metastasis is an important consideration in the diagnostic work-up and treatment of patients with known systemic malignancy who present with a new intracranial lesion. This pathologic entity could be missed if this patient were treated with single-fraction radiosurgery such as Gamma Knife.

Variable Moyamoya disease (MMD) genotypes and phenotypes between different races have been suggested previously. This study investigates differences in surgical complications and response to revascularization among Asian patients with MMD compared with other ethnicities in North America. ⋯ Asian patients with MMD may be more susceptible to surgical complications and may differ from other races in their response to revascularization. Further long-term prospective studies are needed to investigate these findings.
