Question : I recently had an ultrasound and there was a shadow of "prominence" showing up in my right kidney in the lower pole, renal pelvis area. The radiologist recommended a CT scan to evaluate further. What are the possible reasons for the shadow showing up on the right kidney? Thank you for your time.
Brief Answer:
Primary consideration for shadowing is stones.
Detailed Answer:
Good Day!
Primary consideration for shadowing in a kidney ultrasound are kidney stones. Kidney stones is the most common cause of shadowing when the ultrasound transducer hits the stone, it will cause shadowing.
Another diagnosis that could produce a shadowing would be a prominent column of bertin. This is a normal condition where in the structures inside the kidney are more prominent than usual. This prominence would reflect on the ultrasound as shadowing also.
I would also suggest getting a CT scan since it has 95% chance of detecting even the smallest kidney stones or lesions. It would give us a right diagnosis and a peace of mind. I Hope I have answered your question and thank you very much.
