Neuroimaging findings from a case of neurocysticercosis

Abstract

Introduction: Human cysticercosis occurs when humans ingest Taenia solium eggs from the fecal-oral route. The infection in the central nervous system is called neurocysticercosis and is considered the principal cause of late-onset epilepsy in endemic countries in Latin America, Asia, and Africa. Case report: 71-year-old female in a state of neglect with a medical history of untreated rheumatoid arthritis. She presented her first seizure episode. Cerebral magnetic resonance imaging with contrast reported parenchymal and subarachnoid neurocysticercosis in different stages. Discussion: The high incidence of neurocysticercosis in endemic countries is associated with poverty conditions such as less hygienic conditions and permanent contact with domestic animals. The four stages of classification of neurocysticercosis is useful for pathologists and radiologists to identify the life cycle of the parasite within the body and the specific imaging findings of each phase. After diagnosis, treatment includes the use of niclosamide or praziquantel. Conclusions: neurocysticercosis is a public health problem in endemic countries that requires further attention. Clinical manifestations are variable and neuroimaging findings are essential to making a correct diagnosis.
