title: [Neurocysticercosis with hydrocephalus and secondary bilateral hemianopia].
abstract: METHODS
  A 45-year-old woman with a history of seizures, headaches, nausea, vomiting, and decreased visual acuity of 5 years. Visual field detected a bitemporal heteronymous hemianopia. Magnetic resonance imaging revealed basal cistern arachnoiditis and supratentorial hydrocephalus. Cranial computed tomography revealed supratentorial calcifications, scolex in the left occipital region, and hydrocephalus secondary to entrapment of the fourth ventricle.
  
  
  CONCLUSIONS
  Neurocysticercosis can cause bitemporal hemianopsia due to chiasmatic compression secondary to obstructive hydrocephalus. The positivity of anti-cysticercus antibodies determined by ELISA evidence active disease. However patients with hydrocephalus and negative antigen may have sequelae of infection with non-living parasites.
