the presence of fistulas as complications of abdominal aortic aneurysms (AAA) is a known condition, however, infrequent. An incidence of 1 % for aortocaval fistulas (AFC) has been reported in the literature, or even lower values are found in some case series. The aim of this study is to review the literature based on a clinical case to present the diagnostic approach and imaging findings of AFC in order to familiarize readers with the most common characteristics of this entity by computerized tomography. We present the case of a 59-year-old female patient with a clinical picture of four-day evolution abdominal pain, with no relevant history. The abdominal physical examination identified the presence of a pulsatile mass associated with abdominal murmur as the main findings. Abdominal TC angiography assessment identified fusiform aneurysmal dilatation of the abdominal aorta with fistula to the inferior vena cava (VCI), and involvement of the right renal artery with ipsilateral renal hypoperfusion.

Keywords : aortic aneurysm; abdominal; vascular fistula; rupture; vena cava.
