The data on arachnoid cysts in children (0–15 years) operated upon between 1980 and 1988 were analysed in a retrospective, co-operative study. The results from 285 patients indicate a predominance of these lesions in boys (64%) more than girls (36%) and a mean age of 6 years at onset of symptoms. Focal EEG patterns corresponding to the cyst's location were(More)
A total of 911 Danish children under 15 years of age were treated for an intracranial tumour in the 25-five year period 1960–1984. All cases were followed up to the end of 1994 or to emigration or death if one of these came sooner. The mean annual incidence was 32.5 per million children with a slight increase over the 25 years. The male/female ratio was(More)
BACKGROUND Over years, surgical training is changing and years of tradition are being challenged by legal and ethical concerns for patient safety, work hour restrictions, and the cost of operating room time. Surgical simulation and skill training offer an opportunity to teach and practice advanced techniques before attempting them on patients. Simulation(More)
Medulloblastoma is a common paediatric brain tumour, located in the cerebellum and in the IV ventricle, surpassed in frequency only by astrocytomas. 180 children below the age of 15 with a medulloblastoma of the posterior fossa were treated in Denmark in the 25-year period from 1960 to 1984 and followed up until the end of 1996, or until death. During the(More)
A rare case of papilledema associated with a large sacral intraspinal cyst is described in a 34-year-old male. Symptoms were aggravated by heavy work and consisted of low back pain, headache, dizziness and episodic vomiting. Papilledema was observed on ophthalmological examination. A valvular mechanism was found to exist between the normal spinal sac and(More)
A large traumatic brain abscess in a 9-year-old white boy was successfully treated conservatively with antibiotics, including metronidazole and ampicillin. No neurological or psychological sequelae, except for unilateral loss of the olfactory sense, were revealed at follow-up 5 years later, and on CT two minor hypodense areas remained in the right frontal(More)
The series studied comprises all 851 patients with symptom-producing intracranial saccular aneurysms admitted to the departments of neurosurgery in Denmark in the five-year period of 1970–1974. The series was divided into seven clinical stages according to Hunt's classification. More than half of the patients were grouped in stages IV and V (Hunt grade(More)
Three cases of lumbar spine fracture following Conray® radiculography are reported and discussed together with a survey of the literature. It is concluded that Conray® is hardly the ideal contrast medium for lumbar radiculography. It is suggested that the dimerisation proeuct of Conray® — Dimer-X® — be used instead. The injection of contrast material should(More)
