**3. Etiology**

The appearance of PPC parallels that of pancreatitis and the etiology is strictly associated with the causes of pancreatitis. Typically, the PPCs form as a result of pancreatic duct disruption with subsequent fluid leakage or by the maturation of peripancreatic necrosis. Ninety percent of them occur in the context of pancreatitis, while only 10% are caused by trauma (surgery, gunshots, and blunt abdominal trauma) [6]. Regarding the acute pancreatitis, PPCs formation (approximately 15%) is infrequent
