Abstract:
Objective To observe prenatal ultrasonic findings of fetal malformation of cortical development(MCD).Methods Totally 37 singleton fetuses with MCD diagnosed by fetal cranial MRI and/or genetic examination were retrospectively enrolled,and prenatal ultrasonic manifestations were observed.Results Among 37 fetuses,29(29/37,78.38%)were found with abnormal Sylvian fissure,26(26/37,70.27%)with widened/asymmetrical lateral ventricles,22(22/37,59.46%)with abnormal surface sulci,14(14/37,37.84%)with abnormal cavity of septum pellucidum(CSP)/corpus callosum(CC),11(11/37,29.73%)with midline deviation/curvature,11(11/37,29.73%)with widened subarachnoid space,10(10/37,27.03%)with head circumference<2 standard deviation below mean value,9(9/37,24.32%)with abnormalities in the cerebellar hemisphere/vermis,7(7/37,18.92%)with abnormal echoes in the brain parenchyma,7(7/37,18.92%)with midline cysts and 2(2/37,5.41%)with enlarged ganglion eminence.Conclusion Fetal MCD mainly presented as abnormal Sylvian fissure,widened/asymmetrical lateral ventricles and abnormal surface sulci,which might accompanied by abnormal CSP/CC,midline deviation/curvature,widened subarachnoid space and abnormal head circumference in prenatal ultrasound.
