Fluid Collections and Pseudocysts as a Complication of Acute Pancreatitis.

Pseudocysts evolve from fluid collections and/or disruptions of the pancreatic duct. They may occur secondary to acute pancreatitis, pancreatic trauma, or chronic pancreatitis. Lacking the clinical information, radiologists may inappropriately call a fluid collection or any cystic lesion a pseudocyst. With no clear history of acute pancreatitis or chronic pancreatitis, this is rare. Complications include infection, intracystic hemorrhage, or rupture. Pseudocysts can become painful, especially with chronic pancreatitis, and can cause early satiety and weight loss when their size affects the stomach and bowel. Symptomatic pseudocysts can successfully be drained with via surgical, radiologic, or endoscopic drainage.
