Historical Article
[History of the Société Française de Neurologie: 1899-1974].
The "Société de Neurologie de Paris", started by 17 founding members all of whom with the exception of Dejerine were students of Charcot, helds its inaugural session on 6th July 1899. It became the "Société Française de Neurologie" in 1949. Its history is intertwined with that of neurology itself, to whose progress it greatly contributed through the work presented at its monthly sessions and collated in the Revue Neurologique, "the official organ for its publications". ⋯ However, it is within the context of the Society that the wide range of neurosciences can find the federating influence they need to take their place within the corpus of neurology. The history of the Society has also reflected the century through which it has lived, a century which has proved one of the most tragic in the history of the western world. It has suffered its many vicissitudes, which have been fundamental in determining the nature of its work and its sphere of influence.

Neurological sequelae reported after epidural anesthesia include epidural hematoma, spinal cord ischemic injury and lumbosacral nerve root injury. We describe here a case of monoplegia of the right lower limb associated with an ipsilateral loss of perception of pain and temperature following an epidural anesthesia. ⋯ Hypotension, vascular spasm, trauma, arteriosclerosis, pressure increase in the epidural space are potential causative mechanisms. Unilateral symptoms might result from injury to a sulcocommissural artery or an anterior spinal artery when duplicated.

Review Case Reports
[Motor neuropathy, putamen necrosis and optic nerve atrophy after acute methanol poisoning].
Optic neuropathy and putaminal necrosis are the most common sequellae of methanol poisoning. We report a case in a patient with a chronic motor neuro(no)pathy in addition to these neurological complications. Peripheral nerve and spinal cord disorders, related to methanol poisoning, are uncommon and probably underestimated.

Review Case Reports
[Bilateral intracranial subdural hematoma following lumbar puncture: report of a case].
A chronic, bilateral, intra-cranial subdural hematoma was diagnosed in a 28 year old man. A standard diagnostic spinal tap had been performed 6 weeks before. There was no other etiologic factor. ⋯ Outcome was fatal in 9 of them. The possibility of an intra-cranial subdural hematoma has to be considered in case of prolonged or unusual headache following a lumbar puncture, even with a headache-free period, knowing the emergency of the surgical therapeutic procedure. The most likely mechanism is subdural venous bleeding induced by the chronic intracranial hypotension due to the persisting lumbar meningeal wound.

Magnetic resonance imaging represents voxels (volume elements) of the body placed in a magnet, by their magnetization determined under various acquisition conditions weighting the contrast of the image by the density of free water protons and their relaxation times T1 and T2. Thus, the sensitivity in depicting lesions is high but pathological specificity is poor. Efforts are made to increase the diagnosis powerfulness of M. ⋯ R. diffusion imaging and functional M. R. I. are intensively under investigation for a better analysis of these different factors conditioning the reversibility of the patient disability.
