Aneurysm of the inferior vena cava

Case contributed by Dr Domenico Nicoletti

Presentation

Incidental finding.

Patient Data

Age: 70 years
Gender: Female
X-ray

There is a round opacity at the right cardiophrenic region.

There is aneurysmal dilatation of the suprahepatic segment of the inferior vena cava (IVC).

Case Discussion

This case demonstrates a type I IVC aneurysm (Gradman and Steinburg classification). Most of these IVC aneurysms are idiopathic. Some are congenital, while others are caused by trauma or arteriovenous fistulae. The suprahepatic variant of these aneurysms is usually discovered as an incidental mass in the lower mediastinum, just behind the heart.

Patients are usually asymptomatic, but occasionally an aneurysm may be the site of thrombus formation.
