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] .

Jul 1, 2021 · Categorize calvarial lesions according to their extent, multiplicity, and attenuation. Recognize those calvarial lesions with characteristic features to make a definitive diagnosis.

Intraosseous lesions of the calvarium are often slow, progressive processes that manifested in swelling, local pain, or sensitivity disorders. Asymptomatic processes are often described as random findings in the imaging. A variety of diseases can hide behind such a lesion.

Oct 30, 2023 · This article will discuss the anatomy of the calvaria. The frontal bone forms the anterior most part of the superior skull and overlies the frontal lobe. The frontal crest is a ridge in the anterior squamous portion of the frontal bone and is formed by the convergence of the two ridges of the superior sagittal sinus.

In this article, we will review the imaging features of both common and uncommon calvarial lesions, as well as mimics of these lesions found in clinical practice. • Skull lesions are usually discovered incidentally; they can be benign or malignant. • Metastases are the most frequent cause of skull lesions.

Aug 5, 2024 · Congenital calvarial defects are a group of disorders characterized by congenital calvarial bone defects that vary in severity. CT with 3D shaded surface reformats is the best imaging tool as it demonstrates calvarial defects and bone margins: acalvaria: absent superior osseous cranial vault and dura matter.

By osteological tradition, the calvarium is the cranium minus the face (splanchnocranium) while the calotte is the calvarium minus the neurocranial base. Thus, the calvarial dermatocranium includes the frontals, parietals, interparietal, lamina obturans of the alisphenoids, and squamosals.

The calvaria comprises the frontal, parietal, and parts of the temporal, occipital, and sphenoid bones. These bones are formed by intramembranous ossification, with the exception of noncalvarial parts of the occipital, temporal, and sphenoid bones, which are formed through endochondral ossification.

Jul 1, 2021 · Calvarial abnormalities are usually discovered incidentally on radiologic studies or less commonly manifest with symptoms. This narrative review describes the imaging spectrum of the abnormal calvaria.

Nov 27, 2011 · With an increased understanding of genetic and molecular biology, treatment paradigms for calvarial issues may change. The objective of this paper is to discuss the embryological development and anatomy of the human calvaria and to provide an overview of pathologies associated with this structure.
