The appearance of copper beaten skull is associated with raised intracranial pressure in children. Convolutional markings may be normal but are usually confined to the posterior part of the skull's inner table.
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, a pathology that causes raised intracranial pressure may be the primary cause of copper beaten skull; these include, but are not limited to:
Rather than the inner table of the skull being smooth, there are convolutions that overlie the gyri. As described above (and seen in the differential diagnosis case), convolutional changes may be normal if they are confined to the posterior calvaria and are subtle.
3D volume rendered reformats demonstrate a calvaria with similar appearances to hand-beaten copper pot bottoms.
