**Core Concept**
Autosomal dominant polycystic kidney disease (ADPKD) is a genetic disorder characterized by the growth of numerous cysts filled with fluid in the kidneys, leading to kidney enlargement and potentially kidney failure. The disease also affects other organs due to the accumulation of cysts, which is a result of mutations in the PKD1 or PKD2 genes.

**Why the Correct Answer is Right**
The correct answer is related to the organs commonly affected by ADPKD. Cysts in ADPKD are typically found in the kidneys, liver, pancreas, and occasionally in other organs like the ovaries and testes. The liver cysts are usually asymptomatic and often do not cause any significant clinical problems. However, the presence of cysts in the pancreas is relatively rare and is often associated with complications like pancreatitis or pancreatic cancer.

**Why Each Wrong Option is Incorrect**
**Option A:** Liver cysts are a common finding in ADPKD, and they are often asymptomatic. They can increase the risk of liver cancer and liver failure, but they are not rare.
**Option B:** Pancreatic cysts are relatively rare in ADPKD, but they can be associated with complications like pancreatitis or pancreatic cancer. However, the question asks for the organ where cysts are NOT typically present.
**Option C:** Ovarian cysts are a rare finding in ADPKD, but they can be associated with complications like ovarian torsion or rupture.

**Clinical Pearl / High-Yield Fact**
ADPKD is the most common inherited cause of kidney failure, and it affects approximately 1 in 400 to 1 in 1,000 individuals worldwide.

**Correct Answer:** D.
