title: [Intradural lumbar disk hernia. Contribution of 2 cases].
abstract: Two new cases of intradural herniated disks are added to those previously reported in the literature. It's frequency in our casuistry is of 0.27%, similar to that of other series. Predisponent factors and incidence at different levels are reviewed. Acute or subacute clinical on-set, level of lesion and an early surgical treatment seems to influence the evolution of these patients. Recent observations with C.T. with metrizamide and cytological study of L.C.R. with Cytospin suggest a more precise preoperative diagnosis than the myelography. The final diagnosis has been casual after intradural exploration when there were no correlation between the extradural exploration and the clinical and radiological picture. The pathological study of the intradural herniated disk don't differ from the usual extradural herniated disk.
