Increased length of the cavum septum pellucidum (CSP) and in utero infection are each associated with increased risk of schizophrenia. Hence, we examined whether prenatal infections are related to CSP length in schizophrenia patients. In a well-characterized birth cohort, in utero infection was assessed using serologic biomarkers or physician diagnoses. Magnetic resonance images were acquired, and CSP length was quantified by a standard protocol. In utero infection was associated with increased CSP length in exposed schizophrenia cases compared to unexposed cases, suggesting that prenatal infection plays a role in a neurodevelopmental morphologic anomaly that has been related previously to schizophrenia.
