Objective: Contralateral C7 nerve root transfer surgery has been successfully applied to rescue motor function of a hemiplegic upper extremity in patients with central neurological injury. This surgical technique is challenging, and limited anatomical space makes it difficult to manipulate tissues and may lead to higher complication rates. The authors hypothesis a new surgical route in which cervical nerve roots of both donor and recipient sides are exposed from a posterior intradural approach and neurorrhaphy is performed easily and clearly. ⋯ Multiple anastomoses of C7 to various nerve roots on the contralateral side could also be performed within the same surgical field with an interposition nerve graft. Conclusion: The posterior intradural repair idea affords many advantages, the pathway is shorter and more straightforward, which provides more access to multiple nerve roots repair in one surgical field, and is more familiar to many neurosurgeons and spine surgeons. It may potentially be adapted for clinical use.

Background and importance: Ependymomas are tumours arising from the ependymal cells lining the ventricles and the central canal of the spinal cord. They represent the most common intramedullary spinal cord tumour in adults and are very rarely encountered in an extramedullary location. Only 40 cases of intradural extramedullary (IDEM) ependymomas have been reported, all of which were diagnosed pre-operatively as IDEM ependymomas on contrast-enhanced MRI. ⋯ A small residue is now stable at 2.5 years follow-up. Conclusions: Giant IDEM ependymomas are rare entities and pre-operative diagnosis can be challenging in some cases. Surgery represents the main treatment option being resolutive in most cases.

Case Reports
Patient presenting with frontal subperiosteal abscess and headache: a case of Pott's puffy tumour.
Chronic sinusitis can be complicated with erosion of anterior or posterior wall of the sinus; causing Pott's puffy tumour in the anterior, or epidural abscess in the posterior communication. A 65-year old man with a painful swelling in his forehead is presented. Pott's puffy tumour was diagnosed. ⋯ Postoperative course was uneventful. The presented case suggests that treatment of sinus osteomyelitis should comprise immediate surgical drainage and osteomyelitis debridement followed by long-term administration of antibiotics. MRI study with contrast should be obtained to rule out epidural abscess and dural infiltration.

There is an abundance of articles published on low-grade glioma. The aim of this study was to identify and review the 50 most-cited articles on low-grade glioma, and to perform a bibliometric analysis. ⋯ We identified the top 50 most-cited articles on low-grade glioma and the level of knowledge about this topic has been increased.

The standard methods for measuring intracranial pressure (ICP) are invasive in nature. Non invasive methods such as ONSD may help circumvent these complications and may serve as a surrogate marker for increased ICP. The primary aim of this study was to assess the ONSD (optic nerve sheath diameter) changes using ultrasonography (USG) and computed tomography (CT) scan in hydrocephalus patients before and after the insertion of VP shunt. ⋯ In patients with hydrocephalus undergoing VP shunt surgery, we found a significant reduction in ONSD after the shunt insertion in both pediatric and adult population. We also found a good correlation between the USG and CT scan measurements of ONSD.
