CT-scan images with 3D reconstruction demonestrating unilateral flattening of the right frontal bone with abnormal fusion of right coronal suture and elevation of the superolateral border of orbit on the affected side with upward rotation of lesser wing of sphenoid (harlequin eye deformity). The cerebral hemispheres appear slightly asymmetric, although no frank loss of parenchymal volume is seen.
