Which imaging finding is listed as a renal vascular pathology sign related to the main renal artery?

• A. Renal artery occlusion
• B. External iliac artery
• C. Absence of a visible main renal artery
• D. ESP

Answer: (C)

The key idea is that how the renal arteries appear on imaging reflects the blood supply to the kidney. If you cannot see the main renal artery on Doppler or other vascular imaging, it signals a vascular abnormality of the main renal artery—such as it being occluded, severely stenosed, or even not visualized due to agenesis or technical factors. This absence of a visible main renal artery is a direct imaging sign pointing to a renal vascular issue. The other options don’t fit as imaging signs tied to the main renal artery: the external iliac artery is not the renal artery, and ESP isn’t a recognized renal vascular sign.
