Overview
USG
- Advantages of ultrasonography:
- Disadvantage:
- Cannot detect cysts less than 1 cm in diameter
- 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.
