Conference paper


In adults, ARNOLD-CHIARI malformations (A-CM) are incidentally associated with clinical signs of intracranial hypertension. However, some cases of papilledema (1, 3) and some others with clinical signs of “paroxysmal intracranial hypertension” (3, 13) have been recently reported. In almost all these cases, the ventricular size was not enlarged (1, 3, 12, 13). So the CSF pathways might be clinically and radiologically presupposed normal, implicating that the mean CSF pressure is also normal. Therefore, concerning the late clinical evolution of these malformations, a certain controversy remains on the hydrodynamic effect of the tonsillar herniation (4, 6, 7, 8, 14) that clearly defines A-CM, we studied the CSF dynamics of adult patients suffering from A-CM with or without associated hydromyelia.
