OBJECT Intramedullary spinal cord metastasis (ISCM) is a rare but devastating complication of cancer. Due to both widespread MRI availability and longer survival of cancer patients, the probability of discovering an ISCM during the course of the disease has increased and raised issues regarding the management of these patients, and particularly the place of(More)
Supradiaphragmatic adrenocorticotropic hormone (ACTH) secreting pituitary adenomas are exceptionally encountered (14 cases previously described) and raise issues concerning their nosology and management. If surgery is the treatment of choice, the nature of surgical approach (craniotomy, transsphenoidal approach) remains controversial. To illustrate this(More)
PURPOSE Diffusion tensor imaging permits study of white matter fibre bundles; however, its main limitation is lack of validation on anatomical data, especially in crossing fibre regions. Our study aimed to compare four deterministic tractography algorithms used in clinical routine. We studied the corticospinal tract, the bundle mediating voluntary movement.(More)
The authors report on 2 cases of delayed compression of the cervical spinal cord by dense scar tissue forming around epidural electrodes implanted for spinal cord stimulation (SCS). This complication has not been previously reported. Myelopathy developed in 2 patients 5 and 16 years after the surgical placement of a cervical epidural electrode. Prior to(More)
PURPOSE Cerebral hemispheres represent both structural and functional asymmetry, which differs among right- and left-handers. The left hemisphere is specialised for language and task execution of the right hand in right-handers. We studied the corticospinal tract in right- and left-handers by diffusion tensor imaging and tractography. The present study(More)
OBJECTIVES To report a case of bilateral subacute subdural hematoma following implantation of intrathecal drug delivery device. MATERIALS AND METHODS We present here the case of a 41-year-old woman with multiple sclerosis and intractable spasticity who developed a bilateral subacute subdural hematoma after the placement of an intrathecal catheter(More)
Perineal neuralgias may be considered as nerve entrapment syndromes, which have been anatomically poorly studied. The pudendal nerve could be compressed between the sacrospinal and the sacrotuberal ligaments. This study tries to find a correlation between the pelvis and the lumbosacral junction morphometry, and sacrospinal and sacrotuberal ligaments(More)
PURPOSE The aim of this paper is to review the literature on direct geniculo-extrastriate pathways with special attention to 3D extrastriate visual areas. METHODS A literature review was realized using PubMed and Google Scholar. "Lateral geniculate nucleus", "geniculo-extrastriate pathways" and "white matter fiber tracts" were among the keywords used.

Animal studies have shown that Listeria monocytogenes can probably access the brain through a peripheral intraneural route, and it has been suggested that a similar process may occur in humans. However, thus far, its spreading through the central nervous system (CNS) has not been completely elucidated. The authors present a case of multiple L. monocytogenes(More)
