USG

• On a USG, the kidneys are massively enlarged and diffusely echogenic bilaterally.
• Corticomedullary differentiation is absent.
• High-resolution USG (linear-array transducer, 7.5 mHz or greater) allows visualization of numerous cylindrical cysts in the medulla and cortex, which represent ectatic collecting ducts.

Autosomal dominant form

• Multiple, variably sized cortical and medullary based cysts
• Renomegaly
• Hemorrhagic cysts are often present
