Background: Spina bifida is a long-known disease arising from the incomplete fusion of the caudal neuropore in the first month of intrauterine life. It is thought to have a multifactorial etiology, the most important of which is folic acid deficiency. In evaluating its etiology, the role of antifolate agents like antimalarial drugs is rarely given a strong mention., Methods/patients: This is a 44-month prospective study of consecutive cases of spina bifida cystica presenting to the Neurosurgery Unit of Nnamdi Azikiwe University Teaching Hospital, Nnewi, South-East Nigeria. Data collection was with a structured proforma from presentation, and collation done with Microsoft Excel broadsheet and data analysis with SPSS and χ2 test., Results: A total of 41 cases of spina bifida were attended to within the period, with 92.7% cases of spina bifida cystica. Most presented by >12-24 months, with a consistent history of maternal ingestion of antimalarial drugs during the first trimester of pregnancy., Conclusion: Spina bifida cystica was diagnosed mostly in children whose mothers ingested antimalarial drugs during the first trimester of gestation. There may be a need to critically evaluate the contribution of antimalarial drugs to the etiopathogenesis of this malformation and develop safer antimalarial treatment in pregnancy., (Copyright © 2012 S.
