P11.03: Agenesis of the septum pellucidum: prenatal diagnosis and outcome.

The purpose of this study is to describe imaging findings in a group of fetuses with suspected ASP and to evaluate the clinical outcome of these children. In 17 patients the ASP was considered isolated and the remaining 30 had associated malformations involving the CNS (24) or other organs (6). 14 patients with isolated ASP were delivered, 13 are developing normally, one has developmental delay and three were lost to follow up. 13 patients with associated CNS malformation were delivered (normal development (5), abnormal (6) and no follow-up (2)). Current imaging techniques are not able to provide an accurate prognosis in cases when ASP appears isolated. [Extracted from the article]
