Convolutional markings are normal impressions of the gyri on the inner table of the skull. They appear during the period of rapid brain development, typically between 3 and 7 years of age 4. They are seen predominantly posteriorly.
Anterior involvement of the skull is referred to as a copper beaten skull and suggests the presence of raised intracranial pressure.
