Objective: Meningioma is the most common intracranial tumor in the elderly. Its incidence rate increases with age; so as life expectancy increases, meningiomas are diagnosed more frequently. A comparison is made between 4 outcome scales in this study: Clinical-Radiological Grading System, Geriatric Scoring Scale, SKALE (Sex, Karnofsky, ASA, localization and edema), and the Charlson score, to analyze which patients could benefit from surgery., Materials and Methods: A total of 52 patients of 65 years and older operated in our hospital between 2002 and 2012 were identified, and a retrospective analysis was performed. All individual variables were collected and applied the scales to see their relationship with 3 month and annual mortality. The critical values of each scale were applied and their positive and negative predictive values were calculated., Results: From the four scales, only the Clinical-Radiological Grading System and the SKALE had a significant statistical result when annual mortality was analyzed. None of them were associated with 3 month mortality. There was no statistically significant association between mortality and sex, edema, previous clinical history, and tumor location. But there was an association with age, tumor size and previous Karnofsky., Conclusion: The SKALE and the Clinical-Radiological Grading System are easy tools that can give an insight as regards patients who can benefit from a surgical treatment. Nevertheless, individualized patient analysis and neurosurgeon experience still have great importance., (Copyright © 2014 Sociedad Española de Neurocirugía. Published by Elsevier España.

We report the case of a 32-year-old patient complaining of chronic low back pain radiating to his left thigh. His MRI showed a lytic L1 vertebral body injury. A transpedicular biopsy confirmed the diagnosis of giant cell tumor. He underwent a L1 vertebrectomy and vertebral body replacement with a titanium cylinder using anterior approach, followed by the removal of the L1 posterior arch and the placement of pedicle screws through a posterior approach. The giant cell tumor is a rare benign primary bone tumor that can be locally aggressive and can potentially spread to other areas, usually to the lungs. Although it most frequently affects long bones, approximately 10% of tumors are located in the spine. To minimise the risk of recurrence, the elective management option is surgery., (Copyright © 2014 Sociedad Española de Neurocirugía. Published by Elsevier España. All rights reserved.)

Multiple and self-inflicted penetrating brain injuries (PBI) rare. PBI are rare. We report the case of multiple self-inflicted PBI in a 45 year old man caused by a nail gun. He was admitted to after shooting four nails into his head and one into his thorax. We review the literature on the topic and describe how this case was successfully managed in our hospital.

Primary dural lymphomas are rare. Usually they present themselves as diffuse lesions and are infrequently well-delimited. We present a 44 year old male, who was admitted into our Centre after a generalised seizure. Neuroimage studies (CT scan, MRI and angiography) were performed, demonstrating a right hemispheric well-delimited extra-axial mass, being diagnosed initially as meningioma. The patient underwent surgery with radical scission of the mass and dural margins. Histopathological diagnosis was Non-Hodgkin B-Cell lymphoma (marginal B-Cell lymphoma), which nowadays is considered as MALT lymphoma (Mucosa Associated Lymphoid Tissue). Studies directed to establish tumour extension didn't demonstrate the existence of another lesions in the organism.
