This work aims to prospectively record all primary central nervous system tumors (PCNST), in France, for which histological diagnosis is available. The objectives are to create a national registry and a network to perform epidemiological studies, to implement clinical and basic research protocols, and to harmonize the healthcare of patients affected by(More)
Between 1981 and 1984, 44 patients underwent acoustic neurinoma removal by a posterior cranial fossa approach with an attempt to preserve hearing. Seven tumors were small (less than 20 mm), 28 were medium (20 to 40 mm), and 9 were large (greater than 40 mm). Preoperatively, 4 patients had normal hearing, 15 had serviceable hearing, 10 had poor hearing, and(More)
Eleven of our own cases of tuberous sclerosis with intraventricular tumor and 34 cases from the literature are reviewed. Initial symptoms and identification of tuberous sclerosis and tumor are reviewed. Results of surgical treatment, including direct radical excision and shunting are given. On gross examination, the tumor was most often loosely connected to(More)
BACKGROUND AND PURPOSE Individual rupture risk assessment of intracranial aneurysms is a major issue in the clinical management of asymptomatic aneurysms. Aneurysm rupture occurs when wall tension exceeds the strength limit of the wall tissue. At present, aneurysmal wall mechanics are poorly understood and thus, risk assessment involving mechanical(More)
UNLABELLED The aim of the present study was to determine the clinical feasibility of integration of stereotactic SPECT (sSPECT) with 201Tl in the stereotactic MRI (sMRI)-based planning of brain tumor biopsy. Furthermore, the predictive value of the integrated techniques was analyzed by comparison with the corresponding histologically determined metabolic(More)
This work is based on the microscopic study of 30 trochlear nerve trunks (15 heads). In 17 cases, the trunk arose from two nerve bundles, in 8 cases from one bundle, and for the other 5 nerves, three or four bundles. The mean total length of the trochlear nerve was 86 mm. The nerve may be separated into the 3 following parts: infratentorial, intracavernous,(More)
PURPOSE We prospectively reviewed the clinical results of acutely ruptured cerebral aneurysms treated with GDC over a 5 year period, in order to characterize death and dependency factors. METHODS Between 1997 and 2002, 229 patients (254 aneurysms treated, 140 females, 89 males; mean age: 51 years) with aneurysmal subarachnoid hemorrhage were treated with(More)
OBJECTIVE Metastases to the spine are a common manifestation of breast cancer leading to considerable reduction in the patient's quality of life. Physicians must consider the different treatments available to decrease pain, reduce tumor burden, and ensure spinal stability to prevent neurological compromises. The first objective of this study is to analyze(More)
Between January 1990 and February 1992, a total of 301 patients underwent discectomy for lumbar disc herniation; 29 had an extreme lateral herniation, i.e., foraminal or extraforaminal. The intervertebral foramen is a three-dimensional area demarcated primarily by the pedicles; we call it the lateral interpedicular compartment. The extraforaminal zone is(More)
We propose to evaluate the effect of sacral percutaneous thermorhizotomy on cerebral palsy children. A prospective study including 29 children followed by a multidisciplinary team was conducted from 1990 to 2000. A thermal radiofrequency lesion of the first sacral root was obtained by percutaneous puncture of the posterior intervertebral foramen with(More)
