Answer

Renal ultrasounds are performed to assess change in AMLs or cysts, in the hope that this will allow operative intervention prior to development of renal failure.

Due to under-recognition and underestimation of AML occurrence and size, renal ultrasound is losing favor and is being replaced by abdominal MRI.

Small renal cysts and AMLs usually do not grow significantly until after puberty, and often not until the third or fourth decade of life.

In the author's practice, abdominal MRI is obtained every 2–3 years, concurrent with brain MRI. Studies are obtained more frequently if clinically indicated.
