Hyperostosis frontalis interna is a common, benign thickening of the inner side of the frontal bone of the skull. It is found predominantly in women after menopause and is usually asymptomatic. Mostly frequently it is found as an incidental finding discovered during an X-ray or CT scan of the skull.
Cast of the Peking Man skull, showing the keel continuing onto the frontal bone Sagittal keel as seen in modern Homo sapiens. In the human skull, a sagittal keel, or sagittal torus, is a thickening of part or all of the midline of the frontal bone, or parietal bones where they meet along the sagittal suture, or on both bones.
Porotic hyperostosis, is a pathological condition that affects bones of the cranial vault, and is characterized by localized areas of spongy or porous bone tissue. [1] The diploë, or spongy tissue within the bones of the cranium, swells and the tissue of the outer surface becomes thinner and more porous in appearance.
The falx cerebri is a strong, crescent-shaped sheet of dura mater lying in the sagittal plane between the two cerebral hemispheres. [3] It is one of four dural partitions of the brain along with the falx cerebelli, tentorium cerebelli, and diaphragma sellae; it is formed through invagination of the dura mater into the longitudinal fissure between the cerebral hemispheres.
The calvaria is the top part of the skull. It is the superior part of the neurocranium and covers the cranial cavity containing the brain. It forms the main component of the skull roof. The calvaria is made up of the superior portions of the frontal bone, occipital bone, and parietal bones. [1]
A compensatory mechanism involves the movement of cerebrospinal fluid from the cranial vault towards the spinal cord. [31] The volume of blood in the cranial vault is auto-regulated by the brain, and will therefore not decrease that easily. [31] Intracranial pressure will rise as a result of continued brain growth within the rigid skull. [17]
