CT in congenitally-corrected transposition of the great vessels

Abstract

Congenitally-corrected transposition of the great vessels (CTGV) may be detected de novo in adulthood and the plain radiographic findings may be ambiguous or they may be mimicked by a mediastinal mass. CT readily shows the malposition of the aorta and pulmonary artery, and may also show associated congenital heart lesions. The following cases demonstrate the CT findings in CTGV and the distinction of CTGV from conditions resembling it on radiographs.
