 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 objective of our study was to investigate the association between the initial levels of serum S-100B protein and neuron specific enolase and the severitiy of radiologically visible brain damage and outcome after severe head injury.  Admission computed tomography (CT) scans of forty-four patients with severe head injury were analysed. Initial levels of(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)
Surgically acquired foreign bodies are well known but not widely reported. Only seven articles pertaining to this subject were found in the current neurosurgical literature. Are they a denied neurosurgical reality? In this report with a concededly provoking title, the authors elucidate clinical and medicolegal aspects of retained surgical sponges, with(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)
 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)
Lymphoma as primary infiltration of the skull base, especially the clivus, is unusual and rare [1, 2, 4, 5]. However, increasing incidence of atypical lymphoma manifestations have been reported [5]. As cranial base surgery becomes more common, it is important to be aware of lymphoma as a possible differential diagnosis of clivus lesions. This case presents(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)
¶ Objectives. A number of different image-guided surgical techniques have been developed during the past decade. None of these methods can provide the surgeon with information about the dynamic changes that occur intra-operatively. The development of open configurated MRI-scanners leads to new perspectives in the intra-operative management and resection(More)
