No renal tract stones.
Incidental finding of duplicate IVC. The left common iliac vein continues as the left IVC, receives the left renal vein and then drains into the inferior vena cava. There is no associated abnormality of the kidneys.
Additional incidental finding of 22 mm fatty left adrenal adenoma.
It is important to recognise and report a duplicated IVC as it has implications for future vascular interventions. For example, were IVC filters required, two would need to be placed.
In this particular case, there is no associated renal abnormality such as horseshoe kidney.
For lipid rich adenomas of the adrenal glands measuring under 4 cm, where the patient has no underlying malignancy, no follow up imaging is required1.
