Baby born at 30 weeks to 18 years old primigravida of weight 2 kg, died after 48 hours. Apgar scores were 5 and 8 at 1 and 5 minutes. On autopsy, bilateral enlarged kidney with multiple radially arranged cysts were seen. Which of the following finding is expected to be associated with it?
## **Core Concept**
The question describes a neonate born at 30 weeks of gestation with a low birth weight of 2 kg, who died after 48 hours. The autopsy findings of bilateral enlarged kidneys with multiple radially arranged cysts are characteristic of a specific congenital condition. This condition is associated with **Multicystic Dysplastic Kidney (MCDK)**, but given the bilateral nature and description, it more likely points towards **Congenital Polycystic Kidney Disease (PKD)** or another condition with similar renal pathology.
## **Why the Correct Answer is Right**
The description provided points towards a condition known as **Multicystic Dysplastic Kidney (MCDK)** or **Congenital Polycystic Kidney Disease**, but the key detail here is the presence of **bilateral enlarged kidneys with multiple radially arranged cysts**. This condition seems to align more with **Autosomal Recessive Polycystic Kidney Disease (ARPKD)**, which can present with enlarged kidneys and cysts arranged radially. ARPKD often presents in utero or in early infancy and can be associated with poor outcomes, including neonatal death. The radially arranged cysts are a distinctive feature that can help in differentiating it from other cystic renal diseases.
## **Why Each Wrong Option is Incorrect**
- **Option A:** Without the specific details of the options provided, we can infer based on common associations. If an option does not correlate with the renal pathology described or is not commonly associated with congenital renal anomalies leading to neonatal death, it would be incorrect.
- **Option B:** Similarly, if this option does not align with the expected findings in a condition characterized by bilateral renal cysts and early neonatal demise, it would not be the correct choice.
- **Option D:** This option would be incorrect if it does not represent a common association or finding in the context of congenital polycystic kidney disease or a similar condition described.
## **Clinical Pearl / High-Yield Fact**
A key clinical pearl is that **Congenital Polycystic Kidney Disease (PKD)**, particularly **Autosomal Recessive PKD (ARPKD)**, can present with severe manifestations in the neonatal period, including enlarged kidneys and early renal failure. This condition is associated with mutations in the **PKD1** gene (for Autosomal Dominant) and **PKHD1** gene (for Autosomal Recessive), with the latter often presenting more severely and earlier in life.
## **Correct Answer:** .
