Acute callosal angle measured at the level of posterior commissure.
Dilated sylvian fissures with relatively compact narrow sulci at vertex.
Cingulate sulcus sign is noticed in sagittal section.
No obstructive lesion.
Axial image demonstrates Evan`s index = 0.39.
Coronal image demonstrates callosal angle = 76.5°.
Sagittal image demonstrates cingulate sulcus sign.
