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)
BACKGROUND The prognosis of glioblastoma multiforme remains poor despite recent therapeutic advances. Several clinical and therapeutic factors as well as tumour characteristics have been reported as significant to survival. A more efficient determination of the prognostic factors is required to optimize individual therapeutic management. The aim of our(More)
Most intra-cranial arachnoid cysts are quiescent and remain asymptomatic throughout life. Within the natural course of arachnoid cyst evolution, spontaneous resolution has been known to occur rarely, but its frequency is probably underestimated due to lack of systematic detection and long-term observation. We illustrate the spontaneous regression of(More)
OBJECT Peripheral motor axons can regenerate through motor endoneurial tubes of foreign nerves to reinnervate different target muscles. This regenerative capacity has been brought to clinical applications for restorative surgery after nerve or root injury. In this study the authors explore the extent to which nerve cross-anastomosis between lower(More)
OBJECTIVE To assess the effects of Hyaloglide gel (or auto-cross-linked polysaccharide [ACP] gel; Fidia Advanced Biopolymers, Abano Terme, Italy), a hyaluronan-derivative polymer, on peripheral nerve scarring and nerve regeneration. METHODS We performed two surgical procedures in adult rats: 1) neurolysis of the sciatic nerve and separation of its tibial(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)
Anaplastic oligodendrogliomas (AOD) are rare glial tumors in adults with relative homogeneous clinical, radiological and histological features at the time of diagnosis but dramatically various clinical courses. Studies have identified several molecular abnormalities with clinical or biological relevance to AOD (e.g. t(1;19)(q10;p10), IDH1, IDH2, CIC and(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)
Schwannomas are tumors with slowly progressive symptoms, more often painful than associated with neurologic deficits. Involvement of the sciatic nerve mimics chronic sciatic pain due to a herniated disk. If there is no lumbar pain and lumbar MRI is normal, the sciatic nerve must be clinically and radiologically examined all along its course. We report a(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)
