Meningiomas with exclusive or prevalent dural attachment over the transverse-sigmoid sinus junction area represent a well-defined subgroup of posterior fossa meningiomas. This study reports 13 cases of this localisation (10.8% of all infratentorial meningiomas). In this series, six patients (46%) were discovered as an incidental MR finding. One patient with(More)
BACKGROUND Several types of C1-C2 fixation techniques have been described over the years in order to treat atlantoaxial instability. OBJECTIVE To compare the pros and cons of the most popular C1-C2 posterior fixation used today: C1 lateral mass-C2 pedicle screw and rods (Harms) and transarticular screw (Magerl) fixations. METHODS Retrospective review of(More)
Dear Editor, Symptomatic hydrocephalus following spinal intradural surgery is a rare event.

Background and Study Aims Cervical spondylotic myelopathy (CSM) is the most common cause of spinal cord dysfunction in the elderly population. Surgery is usually successful in preventing any deterioration, as well as improving functional status and quality of life. This study assesses the safety and efficacy of minimally invasive microscopic posterior(More)
CONTEXT Surgery for the rheumatoid cervical spine has been shown to stabilize the unstable spine; arrest/improve the progression of neurological deficit, help neck pain, and possibly decelerate the degenerative disease process. Operative intervention for the rheumatoid spine has significantly changed over the last 30 years. AIMS The purpose of this study(More)
OBJECTIVE Large schwannomas with intradural and extradural extensions are often challenging surgical lesions. A variety of approaches, usually requiring large exposures, removal of facets and pars interarticularis, and spinal stabilization, have been described. The aim of this study is to describe the "dual approach," a less invasive technique for the(More)
INTRODUCTION Cauda equina syndrome secondary to lumbar fracture is a relative rare event.
