Corpus callosal dysgenesis

Case contributed by Fazel Rahman Faizi
Diagnosis certain

Presentation

Ultrasound reported hydrocephalus

Patient Data

Age: 3 months
Gender: Female
ct

The lateral ventricles are widely spaced giving a racing car sign on axial images. There is abnormal dilatation of trigones and occipital horns of the lateral ventricles in keeping with colpocephaly. There is also evidence of a high riding third ventricle.

 

Case Discussion

The features are consistent with corpus callosal dysgenesis. On CT, it is difficult to judge whether there is complete or partial agenesis of the corpus callosum. Therefore, corpus callosal dysgenesis is a better term to use rather than partial or complete agenesis of the corpus callosum.

 

Dr. Mohammed Tahir Aien has also contributed to this case.
