Failed Ventriculoperitoneal Shunt: is Retrograde Ventriculosinus Shunt A Reliable Option?
Currently, the treatment of hydrocephalus is mainly carried out through a ventriculoperitoneal shunt (VPS) insertion. However, in some cases, there may be surgical revisions and requirement of an alternative distal site for shunting. There are several described distal sites, and secondary options after VPS include ventriculopleural and ventriculoatrial shunt, which have technical difficulties and harmful complications. ⋯ We propose that in cases where VPS is not feasible, RVSS may be a safe and applicable second option. Nevertheless, the long-term follow-up of patients and further learning curve must bring stronger evidence.

Review Meta Analysis
Effect of Temozolomide and Radiotherapy on Brain Metastatic Tumor: A Systematic Review and Meta-analysis.
To systematically evaluate safety and efficacy of temozolomide plus radiotherapy in the treatment of brain metastasis. ⋯ Addition of temozolomide to radiotherapy could increase ORR in brain metastatic tumors. However, it did not significantly improve PFS or OS in the patients with brain metastases but increased risk of drug-related toxicity.

Review Meta Analysis Comparative Study
Treatment of middle cranial fossa arachnoid cysts: a Systematic Review and Meta-analysis.
To review the literature and analyze the efficacy and safety of 3 surgical methods (neuroendoscopic fenestration, microsurgical fenestration, and cystoperitoneal shunting) for middle cranial fossa arachnoid cysts (MCFACs). ⋯ All 3 surgical methods are effective for MCFACs, but considering safety, neuroendoscopic fenestration may be the best initial procedure.

Review Case Reports
Intramedullary recurrence of a thoracic meningioma - Presentation of an unusual case and review of the literature.
Spinal meningiomas are typically extra-axial, slow-growing, benign tumors that arise from the arachnoid cap cells. Intramedullary spinal meningiomas are exceedingly rare with few cases reported in the literature. ⋯ Intramedullary spinal meningiomas, particularly intramedullary low-grade recurrence of a previously extramedullary tumor, are rare phenomena. Although the pathogenic mechanisms are not well understood, intramedullary recurrence as described in this patient may reflect extrinsic factors related to prior surgical resections in addition to histologic progression. When operating on recurrent extramedullary lesions, aggressive arachnoid dissection may predispose patients to unusual patterns of recurrence.
