Neurocysticercosis: Sensitivity and Specificity

Introduction: Neurocysticercosis is a preventable parasitic infection of the central nervous system and is caused by the pork tapeworm Taenia solium. Humans become infected after consuming undercooked food, particularly pork, or water contaminated with tapeworm eggs, or through poor hygiene practices.

The lack of specificity of the neurological symptoms makes it impossible to diagnose the disease on clinical grounds alone.

PCR may be particularly helpful for diagnosing extraparenchymal NC when neuroimaging techniques have failed.
