Case ReportsIs skull fracture necessary for developing an intradiploic pseudomeningocele as a complication of head injury in adulthood?
We report the case of an adult with a posttraumatic intradiploic pseudomeningocele which caused an expanded osteolytic skull lesion. Local pain and swelling, the only symptoms of the lesion, regressed after surgery. Intradiploic pseudomeningocele must be distinguished from intradiploic leptomeningeal cyst, which is of traumatic origin or arachnoid cyst and epidermoid cyst, which are of congenital origin. We also discuss the development of intradiploic pseudomeningoceleafter head trauma without skull fracture in adulthood and suggest a possible mechanism.

Review Comparative StudyIntra-operative magnetic resonance imaging in neurosurgery.
Intra-operative MRI (iMRI) has been incorporated into modern neurosurgical operating rooms as a guide for neurosurgical interventions for almost ten years. This technology has been shown to be a useful modality in brain tumour surgery and biopsy; its use in spine, vascular and epilepsy surgery has been evolving. ⋯ We evaluate currently available iMRI systems and their applications in neurosurgery. Future possibilities related to iMRI systems are mentioned in the light of current advances.

Astroblastoma is a rare glial tumour about which little is known. ⋯ Classification and histogenesis of this tumour is still debated. The lack of a clinicopathological correlation makes the prognosis of this tumour unpredictable. The optimal management is not defined, but total resection and post-operative radiotherapy seem to be the effective means to treat the astroblastoma.

Selective diagnostic cervical nerve root block--correlation with clinical symptoms and MRI-pathology.
The aim of this study is to describe the method of a cervical selective diagnostic nerve root block (SNRB) technique and assess its ability to correlate clinical symptoms with MRI findings in patients with cervical radicular pain and a single level degenerative disease. ⋯ The block procedure seems relevant for revealing a relationship between radiological pathology and clinical symptoms and signs.

As the number of implanted vagal nerve stimulators grows, the need for removal or revision of the devices will become more frequent. Our purpose was to demonstrate the feasibility of complete removal of the vagal nerve stimulator electrode using microsurgical technique. ⋯ This series suggests that the electrode can be removed from the vagus nerve and repositioned without significant consequence in most cases.
