Agenesis of the corpus callosum

Case contributed by Dr Bita Abbasi

Patient Data

Gender: Male
Modality: MRI

The corpus callosum is absent.

Axial images: The bodies of lateral venticles have a parallel orientation. Fibers of white matter located in the medial side of bodies of lateral ventricles are called "Probst bundle". These are considered as the fibres that meant to make corpus callosum. The posterior parts of lateral ventricles are enlarged; this is called "colpocephaly".  

Coronal images: "Steer horn", and "Viking helmet" signs are made by the frontal horns of the lateral ventricles in the coronal plane.

Sagittal image: Brain sulci have a "sun ray" appearance in the midsagittal plane.
