3 cases of abnormalities of the inferior vena cava are reported: one isolated left inferior vena cava, one duplication of the inferior vena cava with continuation by a left inferior hemi-azygos vein and a simple duplication of the post-renal inferior vena cava. Finally, 2 cases of retro-aortic left renal vein are described. These abnormalities may be fully studied by computed tomography which in certain cases makes it possible to avoid inferior cavography. The authors emphasize potential sources of error in interpretation and the value of being aware of the congenital malformation of the inferior vena cava.

[Value of computed tomography for the investigation and diagnosis of aortic aneurysms (author's transl)].

Abdominal or thoracic aneurysms can be perfectly well visualized by computed tomography, and tumors lying close to the aorta and simulating ectasia can often be eliminated. The exact topographical features of the lesions can be defined as well as their extension superiorly. In many cases, calcifications, clots, a permeable channel, or even a periaortic hematoma showing fissuration can be demonstrated. On many occasions the value of computed tomography is such that angiography may not be necessary.
