ABSTRACT

Diagnosis: Complex Malformation

History: Full-term neonate with abnormal prenatal ultrasound.

Findings: This patient has agenesis of the corpus callosum. The posterior fossa is small, with a normally formed cerebellum, which is compressed inferiorly, and the 4th ventricle and cerebral aqueduct are patent. The globes maintain cross-midline symmetry, and hypotelorism is noted. The optic tracts are normally formed. The thalami are fused, and there is partial interhemispheric fusion of the insular parenchyma, and a suggestion of anterior frontal lobe fusion. There is a partially formed posterior falx cerebri, and anterior interhemispheric fissure. There is a probable large monoventricle with a dorsal interhemispheric cyst, abutting dysplastic cerebral tissue. There is an apparent hypoplastic left internal jugular vein. A cephalocele at the vertex is also noted.

T2 weighted axial image through the posterior fossa reveals the cerebellum is normally formed, and the 4th ventricle is patent.  There is no cleft palate.
