Cerebral palsy. There is a 12 mm wide defect in the inferior right frontal lobe, with abnormal cortex along the margins of the defect. The lateral ventricles are mildly enlarged and display angulated margins. In addition, there is absence of the septum pellucidum. There is no evidence of intracranial hemorrhage, mass, or acute infarct. There is no abnormal intracranial enhancement. There is a posterior pituitary bright spot in the normal location. There is no midline shift or herniation. There is a persistent falcine sinus. The major cerebral flow voids are otherwise intact. The skull, paranasal sinuses, and scalp soft tissues are grossly unremarkable. The bilateral optic nerves appear to be hypoplastic.
1. Right inferior frontal lobe schizencephaly with associated findings suggestive of septo-optic dysplasia and a persistent falcine sinus.2. No evidence of intracranial hemorrhage, mass, or acute infarct.
