To demonstrate the multiple skull vault and scalp lesions,
including anatomical variants,
neoplastic and miscellaneous changes.
To describe the radiological pattern.
To gather this information,
which is scattered in the literature,
thus serving as a tool for the professional radiologist in the differential diagnosis of lesions in these topographies.
Skull vault and scalp lesions are present in every day radiologist,
but in many cases they go unnoticed and when detected generate a great diagnostic dilemma due to non-specificity and unfamiliarity with the findings.
The scalp is composed of five layers: skin; connective tissue; galea aponeurosis; loose connective tissue and periosteum Fig. 1 .
The skull vault can be divided into three layers: outer board,
dipole and inner board.
due to this constitution,
Findings and procedure details
Anatomical variation When unknown,
some anatomical variations may be mistaken for pathologies,
some of which include enlarged parietal foramina and other like cranium foramina; wormian bones; arachnoide ganulation; transcalvarial venous channel; diffuse thickening of the skull; hyperaration of the skull bones. Fig. 2 Fig. 3 Congenital changes in size and shape of the skull Craniosynostosis It is a condition in which one or more of the fibrous sutures prematurely fuses by ossification,...
Skull vault and scalp are sites of anatomical variations and lesions of the most diverse etiologies and with image patterns that sometimes overlap.
the radiologist's knowledge of these standards and having an easily accessible material for research are important for a more accurate diagnosis.
