Neurocysticercosis

Neurocysticercosis is a significant public health issue within the United States. Although cysticercosis was once thought to have been eradicated in the United States, the number of documented cases is rising and immigrants from endemic areas are at the highest risk for acquiring and developing this disease. The clinical presentation of neurocysticercosis is variable and vague neurologic symptoms or sudden unexplained death in individuals with risk factors may be the only available information warranting a consideration of neurocysticercosis. Radiologic and laboratory findings can help guide medical and surgical interventions, while histologic confirmation establishes a more definitive diagnosis. Encysted larvae can be found throughout the central nervous system and undergo progressive stages of decay. Degenerating vesicles elicit an inflammatory response, involving surrounding structures, and cause the major clinical symptomatology.
