- May be unilateral or involve only part of a kidney.[3]

- Renal collecting system forms when ureteric bud (which grows from cloaca) meets the renal blastema (kidney parenchyma precursor).
Gross
- Kidney has multiple large cysts or differing sizes.
DDx:
- ARPKD - has less variability of cyst size.
Images:
Microscopic
- Cystic spaces of variable size.
- Fibrous stroma.
- Islands of cartilage.
