Abstract

Duplication of the inferior vena cava is a rare malformation, normally without clinical impact, explained by abnormal development and regression of certain segments of the venous system during embryonic life. However, its presence and type should be systematically reported in the radiological report because of its potential implications for diagnostic and interventional procedures. This observation describes the case of a 77-year-old man with a complete asymmetric duplication of the inferior vena cava (type III IVC according to Natsis) that was incidentally discovered on CT-scan.

Keywords: Duplication; Imaging; Inferior vena cava.

Abdomino-pelvic CT in sagittal and axial sections in arterial phase: major pre aortic trunk (MPAT) (red arrow) crossing obliquely in front of the aorta, in the aortomesenteric clamp with a physiological angle of about 90 degrees.(Color version of the figure is available online.)

Abdomino-pelvic CT in axial slices in the portal phase: The left and right IVC (B: blue arrows) had a transverse diameter of 13 and 19 mm, respectively, compared with 34 mm for the MPAT major pre-aortic trunk (A: MPAT: red arrow). (Color version of the figure is available online.)
