    Abstract:
    Five patients were studied who suffered secondary hydrocephalus due to neurocysticercosis. Shunt dysfunction was due to the obstruction of the ventricular catheter caused by the own cysticercus cysts. The Biomed system was used in four cases and the Hakim system in one. Valvular dysfunction was observed in patients within a period of 18 to 24 months after surgery, they had a history of several valvular dysfunctions. The diagnosis was made upon of extracting the catheter where the cyst was found to be attached to the ventricular brush. Subsequent evolution has not been satisfactory. The reasons for this complication are of a hydrodynamic and pharmacological nature and are also due to the growth of the cyst. This complication is not often suspected, therefore we recommend that in case of frequent valvular dysfunctions and asymmetrical hydrocephalus, studies like iodinetomography or magnetic resonance imaging be carried out in order to discard this possibility.
