Mild unilateral ventriculomegaly - 28 weeks gestation (fetal MRI)
Updates to Study Attributes
Normal sulcation and operculisation.
OperculisationFurther covering of the insular cortex by the temporal lobe.
SulcationFirst image: the precentral and postcentral sulci (dotted arrows) are now present on either side of the central sulcus (solid arrow).Middle image: further development of the cingulate fissure (straight arrows) and collateral sulcus (curved arrow).Last image: cingulate fissure (dotted line) is in this case well seen on the sagittal series, with continuation into the marginal sulcus (curved arrow). The parieto-occipital (straight arrow) and calcarine (dotted arrow) fissures are also well depicted on this slice.

This case demonstrates isolated, mild unilateral ventriculomegaly.
Normal sulcation for this stage of gestation is demonstrated.
Compare with normal fetal brain MRI scans at 22 weeks, 24 weeks and 26 weeks gestation.
