MRI images showing the absence of the corpus callosum with the medial surfaces of the brain having radial gyri due and cingulate gyrus. The lateral ventricles run parallel rather than the normal "bow-tie" configuration giving a racing car appearance on axial imaging, there is also colpocephaly (dilatation of the trigones and occipital horns) giving a characteristic "longhorn"/moose head/viking helmet appearance on coronal imaging. Remainder brain is unremarkable.
