The objectives of this review are as follows:To illustrate the imaging findings of complications of the acute pancreatitis in computed tomography examination in patients who hadn’t had a clinical manifestation of acute pancreatitisTo demonstrate the various and rare complications of the diseaseTo demonstrate that imaging findings can help to assess the diagnosis of pancreatitis in clinically difficult situations.

• Acute pancreatitis is an acute inflammatory process of the pancreas with regional and systemic involvement, usually with typical clinical profile and symptoms as: epigastric pain radiating to back, fever, nausea and vomiting.• Because acute pancreatitis is a clinical diagnosis, CT is used for confirmation of diagnosis, grading of inflammatory or / and necrosis changes and assesment of complications.• Presented patients were referred to chest or abdomen MDCT with no clinical suspicion of pancreatitis and pancreatitis was diagnosed primarily on basis of imaging findings and...

In this exhibit, we will illustrate the imaging findings of the uncommon pancreatitis complications including: fistula formation, hemorrhage into the pseudocyst, infectious necrosis and pseudoaneurysm formation.Acute pancreatitisTypical CT imaging findings:• Enlarged pancreas with blurred border• Heterogeneous enhancement of pancreas parenchyma• Infiltration of peripancreatic fat1.Complications of acute pancreatitis associated with pancreas• Acute fluid collections• Pseudocyst (and its complications: hemorrhage; infection; rupture)• Sterile pancreatic necrosis• Infected pancreatic necrosis• Pancreatic abscessAcute fluid collections (see imagees 1- 5):Collections of fluid compose of enzyme-rich pancreatic juice• Density usually below 15...

• Contrast-enhanced MDCT is not only the method of choice for evaluation of severity of acute pancreatitis, but is also helpful in diagnosisof its complications and sometimes even able to diagnose pancreatitis in patients with no clinical suspicion of this disease.
