Solid cervicomedullary haemangioblastomas represent a small but technically challenging subset of posterior fossa haemangioblastomas because of their site, high vascularity and tendency to bleed. We present our experience with preoperative embolisation of two solid cervicomedullary haemangioblastomas. In both cases the main feeding artery was the posterior inferior cerebellar artery. Arterial pedicles were catheterised with a microcatheter. The embolic material was small particles (150-250 microm) of polyvinyl alcohol. The result was almost complete preoperative obliteration of the vessels of the tumours. The procedure was well tolerated and facilitated easier bloodless, successful resection in both cases, 24 h after embolisation.

Department of Neurosurgery, Poona Hospital & Research Centre, Maharashtra, India.
Background: Displaced odontoid fractures that are irreducible with traction and have cervicomedullary compression by the displaced distal fracture fragment or deformity caused by facetal malalignment require early realignment and stabilization. Realignment with ultimate solid fracture fusion and atlantoaxial joint fusion, in some situations, are the aims of surgery. Fifteen such patients were treated with direct anterior extrapharyngeal open reduction and realignment of displaced fracture fragments with realignment of the atlantoaxial facets, followed by a variable screw placement (VSP) plate in compression mode across the fracture or anterior atlantoaxial fixation (transarticular screws or atlantoaxial plate screw construct) or both.

Background: Intramedullary schwannomas of brain stem and spinal cord are extremely rare. In almost all cases, homogeneous, asymmetrical or circular intensive gadolinium enhancement has been demonstrated. However, no cases reported previously with minimal contrast enhancement in cervicomedullary junction.

Department of Paediatric Neurosurgery, Nelson Mandela Childrens Hospital, Parktown, Johanessburg, South Africa.
Background: There is a growing body of literature supporting the use of 5-aminolevulinic acid (5-ALA) in the pediatric population, however, its use is still considered "off label" in this setting. In this retrospective study, we report our experience using 5-ALA in pediatric patients with focal brainstem gliomas (BSGs).
Methods: Patients younger than 16 years presenting with a newly diagnosed BSG that was focal in nature were considered suitable for treatment with 5-ALA-assisted surgery.

Introduction: Hemangioblastomas [75% sporadic, 25% with Von Hippel Lindau (VHL) disease] are highly vascular, benign lesions. The surgical nuances, management, and complication avoidance in brain-stem hemangioblastomas (BHs) have been studied.
Material And Methods: Over 18 years, 27(mean age: 29 years; range 15-60 years) consecutive cases of BH underwent microsurgical excision.
Surgical Intervention for Unstable Craniovertebral Junction Anomalies with Narrow C Pedicle.

Department of Neurosurgery, The First Affiliated Hospital of Chongqing Medical University, Chongqing, China. Electronic address:
Objective: We sought to investigate and report a novel surgical technique of screws insertion and posterior surgical reduction, as well as explore its clinical results.
Methods: From September 2008 to September 2012, we treated 41 cases of unstable craniovertebral junction anomalies with a narrow C pedicle at our department. All patients underwent "posterior reduction and internal fixation of the occipital bone with superior or inferior articular process of C and lateral mass of C on the narrowed C pedicle side-for non-narrowed C pedicle side, the screw was only inserted into C pedicle without extending the fixation to C vertebrae-using a titanium screw-rod (plate) fixation system.
