Endoscopic evidence of ventricular and cisternal inflammatory changes after intraoperative cysticercal rupture during endoscopic third-ventriculostomy removal.

Two patients who suffered recurrent hydrocephalus after cysticercal removal by means of endoscopic transventricular (ETV) approach are presented. Severe inflammatory lesions within the ventricular system and basal cisterns, with a patent third-ventriculostomy were demonstrated during a second endoscopic observation. Mandatory shunting with prolonged steroid therapy may be indicated after intraoperative cysticercal rupture after ETV removal, as showed by sequential endoscopic observations.
