Between 1949 and 1982, 290 patients were operated on for lesions of the lower cervical spine. Since 1970 the combined use of the anterior approach and more and more sophisticated osteosynthesis equipment has led us to revise our therapeutic policy with regard to 160 patients. The results, advantages, and disadvantages of this policy are discussed hereafter.
Spinal dysraphia with stretching of the spinal cord is usually diagnosed in the adolescent or young-adult patient. Two types of the condition are distinguished: a stretched spinal cord with an intradural lipoma, and a stretched spinal cord with both an intra- and extradural lipoma. The pathogenesis of the condition and mechanical role of the lipoma and the late appearing neurological signs are presented.
Based on a series of 500 operated intracranial aneurysms in 486 patients, we have analyzed the results of current neurosurgical treatment. The overall results (75% cures, 13% poor results, 12% deaths) depend on several factors, which have all to be analyzed: the age and general condition of the patient; the topography and mode of rupture of the aneurysm; and the timing of the surgical intervention.
A case of post traumatic retrograde amnesia is described. The patient presented after an initial coma a global amnesia, but the fixation deficit rapidly disappeared, and a severe retrograde amnesia dating back to childhood experience and learning remained the main symptom. Amnesia for remote events was associated with didactic memory deficit and, at a lesser degree, with a verbal memory deficit. Recovery of fixation allowed a progressive relearning. This pattern of impairment was recently related to mesencephalic lesions, but we think that the role of temporal lobe involvement cannot be neglected.
A case of giant intrasacral schwannoma is reported. This tumour was revealed by a lumbosacral pain without any neurological deficit. It appears that the lesion is surrounded by a dense layer of nucleated cells which resemble immature cells. This corona of young cells could explain the tremendous size of this tumour.
A case of hemangiopericytic meningioma of the pineal region is reported. We discuss the origin of meningiomas in this region and their histological nature. The rapid recurrence in situ of the tumor in this particular case seems to confirm the need to complement surgery with radiation therapy.
The intradural herniated disc is a rare complication of disc herniation. A study of the literature shows that this location is often responsible for severe neurological deficit with loss of sphincter control and a complete block shown on the myelogram. We report three cases to demonstrate the radioclinical interpretation of intradural herniated disc and the possibility of definite and misleading symptoms.
Seven cases of frontotemporosphenoid meningioma are reported. The principles of the orbitofrontomalar approach and of reconstruction of the orbital cone and of the frontomalar region with an orbitotemporal prop are discussed.

The authors describe a case of brachial plexus'lesion at axillary level in a patient under anticoagulation therapy. They underline the use of CT scan and digitalized angiography to establish the diagnosis and choice the treatment.

Lumbar surgery is currently benefiting from the development of anterior approaches to the spine and the possibilities of body grafts. The transperitoneal approach is being replaced more a more by an extra-peritoneal approach which enables anterior access to the spine. The authors report an antero-internal approach for all the lumbar spine.
Two cases of multiloculated arachnoid cysts of the parietal area are discovered at the ages of 57 and 69. The terrain, the situation and the morphology, the evolution, distinguish these lesions from the more classic cysts of the sylvian fissure. Their pathophysiology is discussed anatomically, these cysts are not far from the post traumatic ones, developing in childhood.
Two personal cases and a review of the literature permit to distinguish by anatomical, clinical and paraclinical aspects : neurilemmoma of the jugular foramen (type III), neurilemmoma of the bulbar spinal (type I), and of the medullary spinal (type II). This classification permits to choice surgical approach.
