Clinical Summary

21 Y/O female with history of pancreatitis 2 month ago and present with abdominal pain , bloating. nausea, vomiting and loss of appetite

Imaging Findings

Ct demonstrated a large localized fluid collections in lesser sac measuring 80 * 80 mm arising in the tail region of the pancreas and extending through the winslow foramen into the greater sac .

Differential Diagnosis

• Organized pancreatic necrosis
• Acute pancreatic fluid collections
• Serous cystadenoma of the pancreas
• Mucinous cystadenoma of the pancreas (see below)
• Mucinous cystadenocarcinoma (see below)
• Pancreatic retention cyst

Final Diagnosis

pseudocyst of pancreas

Discussion (Related Text)

A pancreatic pseudocyst is a circumscribed collection of fluid rich in pancreatic enzymes, blood, and necrotic tissue, typically located in the lesser sac of the abdomen. Pancreatic pseudocysts account for approximately 75% of all pancreatic masses. A pseudocyst isn't a true cyst, because the wall of the sac is not composed of a specific lining of cells characteristic of a true cyst.The most common cause of damage to the pancreas is inflammation, called pancreatitis. A less common cause or contributor is trauma, such as a blow to the abdomen. Pancreatitis is most commonly caused by alcohol use and gallstones.
