Convolutional markings

Last revised by David Luong on 13 Dec 2022

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.
