Neurocysticercosis and Shunt Malfunctions

Authors: Jorge G. Burneo, MD

Abstract

To the Editor: The existence of ventricular shunt malfunctions among patients with neurocysticercosis, mentioned by Psarros et al in the October issue of the Southern Medical Journal, has been previously reported. 1 This is well known to be related to the inflammatory reaction within the subarachnoid space in patients with cysticercotic arachnoiditis, independent of the stage of the infection, and that is the reason why patients with hydrocephalus due to cysticercotic arachnoiditis frequently have a poor prognosis, since the mortality in these patients is directly related to the number of surgical interventions done to replace the shunt. 2
