Clinical and laboratory findings among 34 children (age range from 15 months to 13 years) with neurocysticercosis were reviewed. The main symptoms were: intracranial hypertension, 21 cases (62%); epilepsy, 20 cases (59%); hemiplegia, 4 cases (12%). Computed tomography (CT) in 33 children showed typical brain active cysts in 26 patients (79%) and calcifications in 2 (6%). The complement fixation reaction or the indirect immunofluorescent test for cysticercus antibody were positive in CSF hi 77% (20 out of 26 patients) and serum in 78% (18 out of 23 patients). CSF pleocytosis was found in 57% of the cases (15/26 patients) with eosinophil cells in 27% (7/26 patients). The most efficient diagnostic test was CT scan of the head, and was confirmed immunologically by measurement of cysticercus antibody titers in CSF and serum.
