Absent Septum Pellucidum in Fetal Development: Diagnostic Challenges, Associated Anomalies, and Prognostic Uncertainty-A Structured Narrative Review.

Absent septum pellucidum (absent septum pellucidum) is a rare fetal midline brain finding that may occur in isolation or alongside broader central nervous system (central nervous system) malformations, genetic disorders, or septo-optic dysplasia (septo-optic dysplasia).

This structured narrative review aimed to synthesize current evidence on prenatal imaging findings, associated anomalies, genetic evaluation, and postnatal outcomes in fetuses with absent septum pellucidum.
