What caused patient's complaint?
Oval shaped radio dense 2 x 1.5 cm stone within the pelvis of the left kidney.
Are there other incidental findings?
Yes. A fluid-density non-enhancing retro-crural structure (unusually large cisterna chyli) as well as anomalous origin of the left gastric artery (from aorta), of left hepatic artery (from left gastric artery) and of right hepatic artery (from coelaic artery).
What are the incidence rates of those anomalous origins?
The reported incidence of left gastric artery arising from the aorta is 2-3%, the reported incidence of right hepatic artery arising from the coeliac artery is 1-4% and the reported incidence of left hepatic artery arising from the left gastric artery is 4-11%
Images show:
- an oval-shaped radio-dense stone of about 2 x 1.5 cm size within the left renal pelvis associated with mild back pressure changes
- a well-defined, 4.1 x 3.5 x 2.2 cm, fluid-density, non-enhancing structure within the retro-crural region, that is seen passing through the aortic hiatus being posterior and to the right of the aorta consistent with a large cisterna chyli
- anomalous origins of the left gastric artery (from aorta), of left hepatic artery (from left gastric artery) and of right hepatic artery (from coeliac artery).
