CORTI, Marcelo; VILLAFANE, María F; YAMPOLSKY, Claudio  and  PALMIERI, Omar. Neurocysticercosis with single brain lesions: Report of two cases documented by Magnetic Resonance Imaging and literature review. Rev. argent. radiol. [online]. 2012, vol.76, n.2, pp.161-166. ISSN 1852-9992.

Neurocysticercosis is a central nervous system (CNS) infection caused by the larval stage of Taenia solium. This major parasitic infection is the most common cause of adult-onset epilepsy. The most common clinical manifestations of the parenchymal form of this disease are headache and seizures, whereas extraparenchymal forms typically present with hydrocephalus. In this context, it is important to emphasize that the clinical manifestations of this disease are the result of the death of the tapeworm larvae and of the perilesional inflammatory reaction that occurs in the CNS. The diagnosis of neurocysticercosis is based on epidemiology, clinical manifestations, neuroimaging findings and serology. Treatment of neurocysticercosis includes the use of antiepileptic drugs, corticosteroids and antiparasitic therapy with albendazole or praziquantel. We report two cases of parenchymal neurocysticercosis with single lesions presenting with headache and seizures.
