Intraventricular neurocysticercosis causing obstructing hydrocephalus.

Neurocysticercosis is a parasitic infection caused by the larval stage of the pork tapeworm Taenia solium . Diagnostic criteria for neurocysticercosis are based on clinical manifestations, neuroimaging findings, and epidemiologic exposure. Treatment is tailored to acute symptoms. If increased intracranial pressure is present, then surgical intervention and/or corticosteroids may be used. If seizures are present, then antiepileptic drugs are used for therapy. Antiparasitic therapy is warranted for patients with viable and/or degenerating cysts in the brain parenchyma on neuroimaging. We present a case report of neurocysticercosis causing obstructive hydrocephalus requiring a ventriculoperitoneal shunt.
