**1. Introduction**

Pseudocyst of the pancreas is a localized fluid collection that is rich in amylase and other pancreatic enzymes and is enclosed by a wall of non-epithelialized fibrous tissue. Pancreatic pseudocysts (PPCs) frequently occur in the context of acute or chronic pancreatitis and seldom appear as a postsurgical outcome or trauma. PPCs are less commonly related to acute pancreatitis compared to chronic pancreatitis, due to progressive ductal obstruction while the most common causative factor is alcohol consumption [1, 2]. Computed Tomography (CT) is the diagnostic modality of choice, as it considered to be superior to Ultrasound (US), providing more detailed information regarding the surrounding anatomy. It can demonstrate additional pathology, including pancreatic duct dilatation and calcifications, common bile duct dilatation, and extension of the pseudocyst outside the lesser sac. Complicated PPCs are extremely rare entities but still life-threatening situations, which affect the adjacent tissues of the pancreatic parenchyma. They can lead to infection, hemorrhage, rupture, pseudoaneurysms, pancreatic fistulas, obstructions, and splenic complications. Although they are well described, there is no consensus regarding the "gold-standard" therapy. Therapeutic approaches include conservative treatment(as a majority of cases have been resolved spontaneously), surgical and endoscopic intervention.
