Cornelia de lange syndrome and cerebral dysgenesis. toddler, with severe CdLS and congenital cerebral dysgenesis, in whom no NIPBL mutation was found. Preferred Name. Cerebral dysgenesis Cerebral autosomal dominant arteriopathy with subcortical infarcts and Congenital and peripartum cerebral disorders. Angiography no longer has a role in diagnosis, however, if performed for other reasons may demonstrate an abnormal course of the anterior cerebral artery.

Dysgenesis of the corpus callosum may be complete agenesis or partial and represents an in utero developmental anomaly.

It can be divided into:. A true estimate of incidence is difficult to establish as many isolated cases are asymptomatic. It may be as uncommon as 1: There appears to be a male predilection M: Maternal alcohol consumption during pregnancy has been recognised as another risk factor 6.

Isolated partial dysgenesis of the corpus callosum is often asymptomatic. The clinical picture in other cases is dictated by the associated abnormalities that are frequently found, especially in agenesis 4. Agenesis is a result of an insult occurring at approximately weeks gestation 2,4 resulting in failure to form the corpus callosum.

These bundles of white matter are known as Probst bundles. Dysgenesis which may be complete or partial is a result of encephalomalacia secondary to toxic, ischemic or traumatic events 2. It begins with the genu and then continues posteriorly along the body to the splenium.

The rostrum is the last part ceerebrales be formed. In secondary dysgenesis parts of the corpus callosum which form before the insult will be present whereas later parts will be absent. The presence of the rostrum essentially excludes primary agenesis.

This has diisgenesias termed atypical callosal dysgenesis. As with other structural anomalies, all modalities reflect the underlying morphology, with a greater lesser degree of sensitivity. MRI is the modality of choice in evaluating both the corpus callosum and the frequently associated anomalies.

Angiography no longer has a role in diagnosis, however, if performed for other reasons may demonstrate an abnormal course of the anterior cerebral arterypassing directly posterosuperiorly with widely spaced pericallosal arteriesand absent pericallosal moustache.

The azygos ACA is commonly present in most of the disgebesias. The overall prognosis can be highly variable depending on the presence of other associated anomalies. High-quality MRI essentially eliminates differentials due to the exquisite imaging of the corpus callosum. In the setting of an antenatal ultrasound demonstrating an interhemispheric cyst then the following should be considered The key to distinguishing these entities from a dilated third ventricle with dorsal cyst is identifying the choroid plexus, which demarcates the roof of the third ventricle 5.
