Multicystic dysplastic kidney, abbreviated MCDK, is a cystic disease of the kidney. It is also known as multicystic renal dysplasia (abbreviated as MRD).[1]
General
- Most common cause of abdominal mass in newborns.[2]
- May be unilateral or involve only part of a kidney.[3]
Etiology:
- Embryological malformation.[4]
- Normal development: renal collecting system forms when ureteric bud (which grows from cloaca) meets the renal blastema (the kidney parenchyma precursor).
- In MCDK ureteric bud and renal blastema fail to meet.
Gross
- Kidney has multiple large cysts or differing sizes.
DDx:
- ARPKD - has less variability of cyst size.
Images:
Microscopic
- Cystic spaces of variable size, lined by cuboidal cells.
- Fibrous stroma.
- Islands of cartilage.
Image:
Note:
- Cysts do not communicate with one another.[4]
