Previous studies suggest that neurocysticercosis (NCC), the most common cause of acute symptomatic seizures (ASS), epilepsy and other neuropsychiatric disorders, typically presents with a solitary lesion and focal seizures in children from places where cysticercosis is endemic. We report a series of 3 patients, aged 7 to 11 years, with a history of epilepsy and or recurrent headache referred from Mocuba to the Quaternary Central Hospital in Quelimane, Zambeze Province, Mozambique, an area endemic for cysticercosis. Clinical history and examination, blood chemistry and hemogram screening, serological testing for Cysticercus antigens and antibodies detection, and a computerized tomography (CT) scan, were performed. NCC was confirmed in all 3 patients, based on criteria defined by Del Bruto. Two confirmed cases tested positive for antigen (Ag) by enzyme-linked immunosorbent assay (ELISA) with CT lesions in different stages of parasite evolution. Headache/encephalopathy was present in all patients. This case series of children with epilepsy confirms for the first time the presence of NCC in children from Zambezia province, an east-central region of Mozambique. Further, NCC should be included in the differential diagnosis of children with ASS, epilepsy and other neuropsychiatric disorders. Future studies should be targeted to the identification of biomarkers to support the diagnosis of NCC, given the limited availability of imaging tools and limited value of serological assays for the diagnosis and management of NCC.
