The MRI sequences demonstrate bilateral schizencephaly:
- on the right, there is an abnormal grey matter (polymicrogyria) extending from the cortex to the body of the lateral ventricle with a slight indentation of the ventricular wall, in keeping with a closed-lip variety.
- on the left, the parenchymal defect is lined by heterotopic grey matter with polymicrogyria, extending from the cortex surface to the body of left lateral ventricle with a cleft filled by CSF, in keeping with an open-lip variety
Absent septum pellucidum with small optic chiasma which may represent an associated septo-optic dysplasia.
Case Discussion
The MRI features are consistent with bilateral schizencephaly, closed-lip on the right, and open-lip on the left with polymicrogyria and associated septo-optic dysplasia.
