Neurocysticercosis has been diagnosed increasingly in the United State
s as a consequence of increased immigration from and travel to areas o
f endemic cysticercosis. We report a retrospective series of 47 pediat
ric cases of neurocysticercosis in our large children's hospital in Ch
icago, which has a large immigrant population. Neurocysticercosis was
diagnosed on the basis of any of the following three criteria: (1) sur
gical biopsy findings, (2) radiographic findings consistent with neuro
cysticercosis as well as diagnostic serum and/or cerebrospinal fluid t
iters, or (3) consistent radiographic findings and a compatible epidem
iologic history (without diagnostic serological findings). Epidemiolog
ic, clinical, laboratory, and radiographic data were analyzed. Neurocy
sticercosis is a relatively common cause of afebrile seizures in child
ren who present to our emergency department in Chicago. Computed tomog
raphy and magnetic resonance imaging are both important modalities in
evaluation of children with neurocysticercosis. Laboratory studies are
neither sensitive for nor predictive of the diagnosis of neurocystice
rcosis. Therapy is well tolerated. The long-term prognosis for treated
patients appears to be excellent.
