Cystic schwannoma is highly unusual and intraspinal involvement seems to be even more rare. We report a case of intradural lumbar-cystic schwannoma in a 50-year-old man who presented with chronic low-back pain and sciatalgia, which were initially related to a bulging disc. ⋯ Only eight cases of spinal schwannoma with large cyst have been previously reported. Cystic schwannoma should be considered in the differential diagnosis of lumbar intradural-cystic lesion.

A retrospective study about craniocerebral gunshot wounds was done to better identify outcome predictors. ⋯ This study shows some interesting prognosis patterns: bilateral areactive mydriasis, GCS less or equal to 7 and bullet trajectory (if crossing the midline) are the most important factors predicting a fatal outcome.

Case Reports
[Intracranial hypotension with subdural hematoma following lumbar puncture: case report].
Lumbar puncture is a common procedure highly contributive to neurological diagnosis. It can also cause serious adverse side effects including subdural hematoma and intracranial hypotension as illustrated by this case report. ⋯ The serious adverse effects of lumbar puncture is an easy and common medical procedure that must be kept in mind.

Usual locations of arachnoid cyst are the middle cranial fossa in 50-60%, cerebellopontine angle (10%) and suprasellar area (10%). Most of these malformations are asymptomatic. Premedullar arachnoid cysts are extremely rare. ⋯ Craniocervical junction arachnoid cysts are anecdotic. Medical care cannot be standardized. Pathogenesis and management are discussed.

Neurosurgery remains a very marginal activity in sub-Saharan Africa. In this part of the world which counts nearly 40 countries, some do not have a single neurosurgeon, some have one to five, the number of ten neurosurgeons per country remaining an exception. In its concern of popularizing and of developing neurosurgery worldwide, the WFNS organized an international course in Africa, October 2007 2nd-3rd in Yaoundé (Cameroon). ⋯ Kalangu (Zimbabwe). Twenty three neurosurgeons coming from nine African countries (Cameroon, Nigeria, Gabon, Congo, Niger, Burkina Faso, Ivory Coast, Senegal, and Guinea) took an active part in work. The scientific success of this event led to the creation of the "Association of Neurological Surgeons of Africa (ANSA)" which will be the WFNS-Africa interface in order to insure the development of neurosurgery in Africa.
