OBJECT Patients harboring colloid cysts of the third ventricle can present with acute neurological deterioration, or the first indication of the lesion may appear when the patient suddenly dies. The risk of such an occurrence in a patient already identified as harboring a colloid cyst is unknown. The goal of this study was to estimate the risk of acute… (More)
Cerebellar haemorrhage is an unusual complication of supratentorial neurosurgery. Several causative pre-operative factors and medical risk factors may predispose patients to cerebellar haemorrhage, however its etiology remains still unclear. Only two case reports have previously described the occurrence of cerebellar haemorrhage after subdural haematoma… (More)
We describe a 29-year-old woman who presented with progressive neck pain, sensory deficit and weakness in both arms. Magnetic resonance imaging (MRI) of the cervical spine revealed an extramedullary tumor with severe spinal cord compression. During surgery an intradural extramedullary tumor was found. Further imaging showed a second lumbar spinal tumor.… (More)
BACKGROUND Nerve root decompression with instrumented spondylodesis is the most frequently performed surgical procedure in the treatment of patients with symptomatic low-grade spondylolytic spondylolisthesis. Nerve root decompression without instrumented fusion, i.e. Gill's procedure, is an alternative and less invasive approach. A comparative… (More)
UNLABELLED As the value of grading of ependymomas is currently debated we studied the expression of proliferation- and apoptosis-related proteins in these tumors as these mechanisms both are suggested to be important in tumor growth. We characterized the immunohistochemical expression of p53, Mdm2, Bcl-2, and Bax in 51 intracranial ependymomas. We also… (More)
The authors report a case of multiple meningiomas in a 37-year-old woman with Rubinstein-Taybi syndrome. The patient harbored a bifrontal ossifying meningioma and multiple intracranial meningiomas. She underwent surgery for the frontal ossifying meningioma and a right frontoparietal meningioma.
A 28-year-old man with genetically confirmed hyperostosis corticalis generalisata (Van Buchem disease) suffered from headache and progressive cognitive and sensibility disorders. Bone formation of the skull was ongoing, leading to narrowing of the intracranial space and foramen magnum. A large bilateral frontoparietal craniotomy and decompression of the… (More)
We present a 49-year-old man with a subarachnoid haemorrhage from a dissecting vertebral artery (VA) pseudoaneurysm treated with a proximal balloon occlusion. The clinical course was complicated by the sudden appearance of a lateral medullary syndrome (Wallenberg), which completely resolved after anticoagulant therapy. During this course, CT-angiography… (More)
