School-Age Outcome of Fetuses with Isolated Complete Septum Pellucidum Agenesis at Prenatal Magnetic Resonance Imaging

Objective To the best of our knowledge, there have not been studies to address the issue of long-term follow-up of patients with prenatal diagnosis of isolated complete septum pellucidum agenesis (SPA). The aim of this study was to acquire information about the school-age outcome of such patients as a resource for counseling parents receiving this prenatal finding. Methods From a large fetal magnetic resonance (MR) database, we selected only those cases with isolated complete SPA as confirmed by two senior pediatric neuroradiologists in consensus; we then gathered information from the parents of those children who had reached the school age. Results None among the 12 cases (mean age at follow-up: 8.7 years, range: 6–13 year) of the resulting final cohort presented visual or stature deficits; only one required special teaching assistance in school. All other 11 children resulted without any notable academic issue. Conclusion Our report may provide information of practical value about the school-age outcome of fetuses detected by prenatal MR imaging to carry isolated complete SPA.
