[Intradural spinal arachnoid diverticula and cysts. 6 cases].
3 communicating diverticula and 3 arachnoid symptomatic cyst in intradural situation are presented. In two cases, this pathology is slowly developing, in patients with Von Recklinghausen neurofibromatosis. A congenital malformative process may be evoked. In two other cases, myelography and surgery favor a frank or discreet arachnoïditis. Those establishments show the diversity of mechanisms underlying intradural arachnoïd cysts. They are in most cases in a postero medullary and dorsal situation, but cervical as well as lumbar position are possible. One must insist on the frequency and importance of local and cordonal pain, accompanying in most cases sensory and motor deficits in inferior limbs. A rapid revelation or decompensation is most rare. Prognosis must be reserved, as post operative arachnoïditis and relapse are not rare.
