Radiograph and CT of copper beaten skull
AP and lateral radiographs of the skull (above) show throughout skull vault prominence of convolutional markings from gyral impressions on the inner table of the skull, which is also well demonstrated on the axial CT without contrast of the brain (below).

The diagnosis was copper beaten skull caused by long-standing hydrocephalus in a patient with aqueductal stenosis.
