Abstract

A 37-year-old asymptomatic man presented with incidentally identified intra-abdominal venous aneurysms. Workup, which included venography, demonstrated an absent segment of the inferior vena cava between the inferior right and superior left renal vein, resulting in a 4.4-cm right renal vein aneurysm, dilated common iliac veins, and left external iliac vein aneurysm. Collateralization was robust. Given the limited natural history data and complexities of open reconstruction, we opted to observe this asymptomatic patient with serial imaging, which demonstrated no interval change. We present our case and a review of the literature pertaining to intra-abdominal venous aneurysms.

Keywords: Absent IVC; Renal vein aneurysm; Venous aneurysms.
