 The authors report the case of a 10-year-old girl with intervertebral disc calcifications from the levels C6/C7 to Th1/Th2, presenting with a herniated calcified intervertebral disc at the C7/Th1 level, causing spinal cord compression with subsequent progressive paresis and sensory loss of her left leg. After anterior cervical discectomy and fusion the(More)
The incidence of diagnosed xanthogranuloma of the sellar region is very low [1, 2, 5, 6]. We report about two cases 1) in a 57-year-old female and 2) in a 5-year-old boy. In both cases radiographic findings revealed an inhomogeneous, contrast enhancing sellar lesion. Histopathology showed the typical features of a xanthogranuloma of the sellar region with(More)
The cochlear implant has been shown for some years to be very successful in the treatment of profoundly deaf patients. Cochlear implantation is, however, only beneficial to those patients whose deafness is located in the inner ear. In Hannover to date we have performed implantations in 250 patients, including 61 infants and children using the Nucleus 22(More)
Tumours or vascular lesions of the clivus and juxtaclival region present a unique challenge to neurosurgeons and a variety of techniques, with a wide spectrum of complexity, have been advocated. This report presents the use of a conservative transpetrosal approach which combines partial removal of the postero-lateral petrous bone with preservation of the(More)
¶Summary There is an ongoing discussion about the risk of bleeding from unruptured intracranial aneurysms. Management guidelines were developed recently and some of the recommendations for decision making are based on the anatomical configuration of the aneurysm. The common assumption is that the presence of multiple lobes or a daughter sac indicates a(More)
 Background. To analyse the rate of postoperative haemorrhage during a 4-year period of early postoperative administration (<24 hours) of fractionated heparin plus compression stockings in a large cohort of patients undergoing intracranial surgery.  Method. A total of 1564 patients who underwent intracranial surgery at our institution were included in our(More)
The objective of our study was to investigate S-100B protein as a serum marker of brain cell damage after severe head injury. Eighty-three patients with severe head injury (Glasgow Coma Scale ≤8) were included in this prospective study. Venous blood samples for S-100B protein were taken after admission and every 24 h for a maximum of 10 consecutive days.(More)
Recent experimental studies have shown, that the endothelium of cerebral vessels undergoes significant changes after subarachnoid haemorrhage which may lead to biochemical changes at the endothelial surface with disturbance of the delicate homeostasis of vasodilating and vasoconstricting mechanisms which are thought to be responsible for preservation of the(More)
Subarachnoid haemorrhage (SAH) due to spinal ependymoma is very rare. We report a 37 year old man who presented with typical clinical signs of SAH. Lumbar puncture confirmed SAH but cerebral angiography was negative, and further diagnostic work-up revealed an ependymoma of the conus medullaris as the source of the haemorrhage. A comprehensive review of the(More)
