Case contributed by Prof. Stacy Goergen


Unilateral ventriculomegaly on obstetric ultrasound.

Patient Data

Age: 28w2dGA
Gender: Female

There is mild unilateral lateral ventricular enlargement. No other abnormality was detected in the fetal brain or body (body imaging not shown).

Note the features of normal sulcation for this gestation. New sulci and gyri are developing immediately anterior and posterior to central sulcus. The cingulate sulcus is now visible but superior temporal sulcus not yet seen. The insular cortex is covered further by the temporal lobe as opercularization progresses.
