title: Neurocysticercosis in infants and toddlers: report of seven cases and review of published patients.
abstract: Neurocysticercosis in infants and toddlers has received little attention in the literature, and little is known about the mechanisms of disease acquisition and clinical forms of presentation of the disease in this age group. All patients aged ≤3 years with neurocysticercosis evaluated at Hospital-Clínica Kennedy, Guayaquil, over a 22-year period were included in this study. Their household contacts were screened to detect Taenia solium carriers, which may represent the source of infection. A literature search on neurocysticercosis in infants and toddlers was also performed to compare personal cases with those described elsewhere. A total of 25 infants and toddlers with neurocysticercosis were included (seven from our institution and 18 from the literature). All patients had seizures as the primary manifestation of the disease, and neuroimaging studies showed one or two parenchymal brain cysticerci in the colloidal stage in 88% of patients. The source of infection was investigated in 11 houses, including the seven households of the present series, and only four of the 18 reported in the literature. A Taenia carrier was found in five (45%) of these households, including three from the present series and two from the literature. A sizable proportion of infants and toddlers with neurocysticercosis have been infected at home. Compulsory search of Taenia carriers among household contacts will allow the detection of the potential source of infection and will reduce further spread of the disease. The search must not be limited to family members, but also extended to domestic employees who are in daily contact with the children.
