**Core Concept**
Pseudopancreatic cysts, also known as pancreatic pseudocysts, are fluid collections that develop in the pancreas as a result of inflammation or trauma, leading to disruption of the pancreatic ducts. These cysts are not true cysts, as they do not have an epithelial lining, but rather are contained by a wall of granulation tissue.

**Why the Correct Answer is Right**
The development of a pseudopancreatic cyst is typically a complication of acute or chronic pancreatitis. The inflammation and necrosis of pancreatic tissue can lead to the leakage of pancreatic enzymes and fluid into the surrounding tissue, forming a cystic structure. This process is often accompanied by the formation of a fibrotic wall that contains the fluid collection. The lack of an epithelial lining is a key characteristic that distinguishes pseudopancreatic cysts from true pancreatic cysts.

**Why Each Wrong Option is Incorrect**
**Option A:** Pseudopancreatic cysts are not typically associated with a significant increase in pancreatic enzyme levels. While there may be some elevation in enzyme levels, this is not a characteristic feature of these cysts.

**Option B:** Pseudopancreatic cysts are not usually lined by a layer of cells. Instead, they are contained by a wall of granulation tissue that forms as a result of the inflammatory response.

**Option C:** Pseudopancreatic cysts can be asymptomatic, but they are often associated with abdominal pain, weight loss, and other symptoms related to the underlying pancreatitis.

**Clinical Pearl / High-Yield Fact**
The diagnosis of pseudopancreatic cysts is often made using imaging studies, such as CT or ultrasound, which can help to identify the fluid collection and its relationship to the pancreas.

**Correct Answer: A.**
