The standard treatment guidelines of neurocysticercosis have been described as per computed tomography (CT)-based studies. We aimed to prospectively study if posttreatment magnetic resonance imaging (MRI) clearance rates of neurocysticercosis were like those reported in literature using CT. A prospective observational study in newly diagnosed children with neurocysticercosis was undertaken. Children were treated with antihelminthics and steroids and followed up after 6 months. The primary objective was to study the proportion of children with single-lesion neurocysticercosis who were in radiologic resolution at 6 months and clinical remission (seizure-free for the preceding 3 months). Eighty of 128 consecutive children screened were included (single lesion, 65; multiple lesions, 15). Seventy-two children were evaluated at 6 months. Seizure recurrence was seen in 5 (6.2%). Brain MRI showed an overall clearance of lesions in 10 (14%) children. In the children with single-lesion neurocysticercosis (65), 59 were followed up at 6 months, and lesions resolved in 9 (15.3%, 95% confidence interval of 6.1-24.4). In children with single-lesion neurocysticercosis treated with antihelminthics and corticosteroids, the lesion resolution rate is only 15% at 6 months. Thus, there is a need to review old recommendations and use MRI as a standard outcome measure.
