**Core Concept**
Pancreatic pseudocysts are fluid collections that form in the abdomen due to pancreatic inflammation or trauma. They can cause serious complications if not managed properly, including infection, rupture, and obstruction.

**Why the Correct Answer is Right**
The correct answer includes complications that are directly related to the formation and progression of pancreatic pseudocysts. Infection (A) occurs when the pseudocyst becomes contaminated with bacteria, leading to an abscess. Rupture (C) can cause leakage of pancreatic enzymes into the abdominal cavity, leading to severe chemical peritonitis. Obstruction (D) can occur when the pseudocyst compresses nearby organs, such as the duodenum or stomach, causing bowel obstruction.

**Why Each Wrong Option is Incorrect**
**Option B:** While hemorrhage can occur in the setting of pancreatic pathology, it is not a direct complication of pancreatic pseudocysts. Hemorrhage is more commonly associated with pancreatic necrosis or vascular injury.

**Clinical Pearl / High-Yield Fact**
It is essential to differentiate between pancreatic pseudocysts and true cysts, as the latter have a higher risk of malignancy. A true cyst will have a distinct wall and a well-defined border, whereas a pseudocyst will have a poorly defined border and no distinct wall.

**Correct Answer:** B.
