CLINICAL HISTORY

25-year-old female G4P1A2, 29 weeks of gestation with obstetric ultrasound of concern for ventriculomegaly and schizencephaly.


IMAGING FINDINGS

Examination demonstrated fetus in cephalic vertex position. Placenta was along the posterior uterine wall extending towards the fundus. Sidedness of fetal body was established by cardiac configuration and gallbladder position.
Fetal brain showed bilateral open lip schizencephaly with expanded lateral ventricles at the schizencephaly defects. Larger left perisylvian schizencephaly defect projected outwards from the body of the left lateral ventricle above the left lenticulate nucleus, best demonstrated on coronal series. Contralateral right frontal schizencephaly was more anterior, centred at the opercular margin radiating from the right frontal horn. There was normal-appearing corpus callosum at midline. Third ventricle and fourth ventricle were normal. There was a megacisterna magna behind a normal-appearing cerebellum. Craniocervical junction, cervical and thoracic spinal cord, conus medullaris and lumbar spine appeared normal. (Figures 1, 2 and 3)
