Demographics and clinical presentation
The appearance of copper beaten skull is associated with raised intracranial pressure in children.Convolutional
Pathology
Raised intracranial pressure is (at least in part) the causative mechanism behind increased inner table markings that give rise to the copper beaten skull appearance. Hence, pathology that causes raised intracranial pressure may be the primary cause of copper beaten skull; these include, but are not limited to:
Radiographic features
Rather than the inner table of the skull being smooth, there are convolutions that sit adjacent to the underlying gyri. As described above (and seen in the adjacent case), convolutional changes may be normal if they are confined to the posterior calvarium and are subtle.
3D volume rendered reformats demonstrate a calvarium with similar appearances to hand beaten copper pot bottoms.
