Neurocysticercosis: An Overview of Pathology and Pathogenesis

Abstract

Neurocysticercosis (NCC), a subtle parasite infection of the central nervous system, is a powerful example of the complex interaction between human behavior, zoonotic transmission, and neurological illness development. Given the disease’s worldwide prevalence and potentially fatal neurological consequences, research into NCC is critical for advancing knowledge, creating effective diagnostic tools and treatment options, and adopting preventative measures to lessen the disease’s impact. Cysticerci causes an immunological response in the CNS, resulting in inflammation and immune cell recruitment. The existence of intraventricular cysts, cysts in the cerebral aqueduct or fourth ventricle, and the degree of inflammation and scarring induced by the infection are all risk factors for the development of hydrocephalus. This book chapter provides an in-depth exploration of the pathology and pathogenesis of NCC, discussing the life cycle of the Taenia solium parasite, its invasion of the central nervous system, and the formation of cysticerci, as well as the diagnostic challenges and imaging findings, clinical manifestations, and potential neurological complications associated with NCC, serving as a valuable resource for medical professionals, researchers, and policymakers.
