Changes in fetal intracranial anatomy during maternal pregestational and gestational diabetes

Aim To evaluate the changes in fetal intracranial structures in pregnant women with pregestational diabetes mellitus (DM) and gestational diabetes mellitus (GDM). Methods The study was conducted prospectively with patients who were grouped as pregestational DM (n = 110), GDM (n = 110), and control (n = 110). Fetal ultrasonographic measurements of widths of posterior lateral ventricles (PLV), cavum septum pellucidi (CSP), cisterna magna (CM), thalamus and transcerebellar diameter (TCD) were recorded and compared. Results Fetal PLV, CSP, and CM widths were higher in pregestational DM and GDM groups than in control group, and also higher in pregestational DM group compared to GDM group (p
