Computed tomography of the sternum.

The author presents his experience with computed tomography (CT) in the diagnosis of sternal anomalies. The normal anatomy of the sternum and the peristernal soft tissues are described. The embryology, pertinent to the understanding of congenital sternal anomalies, is reviewed. The technique used to image the sternum is briefly explained. Variants of the sternum, traumatic changes, iatrogenic alterations, inflammation, and neoplastic lesions are illustrated. It is concluded that CT offers definite advantages in the evaluation of presumed sternal pathology and should be the examination of choice in the appropriate clinical setting.
