Are pancreatic cysts and lesions the same thing?
Most pancreatic cysts are benign non-neoplastic (not a tumor) lesions resulting from pancreatitis. However, benign neoplastic (tumor) cysts are slightly more common in women.
What is a cystic lesion in the pancreatic tail?
These cysts are precancerous growths that can start in the body and tail of the pancreas. They almost always develop in women rather than men. Large ones that contain tiny walls that divide the cyst into compartments, called septations, may be more likely to become cancerous.
What does a cystic lesion mean?
Cysts are abnormal, fluid-filled sacs that can develop in tissues in any part of the body. They are relatively common, and there are many different types. Infections, tumors, parasites, and injuries can cause cysts. They are usually noncancerous.
How serious is a lesion on the pancreas?
Most pancreatic cysts are benign, meaning they’re not cancerous, and they arise from conditions other than cancer, like inflammation associated with pancreatitis. However, some cysts are considered “precancerous,” and a small percentage of pancreatic cysts are malignant or can become cancerous over time.
What does it mean if you have a lesion on your pancreas?

Should I be worried about pancreatic lesions?
Thankfully, ruptured pancreatic cysts are quite rare, but they represent an immediate cause for concern. If a cyst ruptures, you need to seek medical treatment immediately. A ruptured cyst is a genuine health care emergency, and can lead to peritonitis, which is a generalized infection in your abdominal cavity.
What are the different types of cystic lesions in the pancreas?
Different types of benign or malignant cystic lesions can be observed in the pancreas. Pancreatic cystic lesions are classified under pathology terms into simple retention cysts, pseudocysts and cystic neoplasms. Mucinous cystic neoplasm is a frequent type of cystic neoplasm and has a malignant potential.
Which physical findings are characteristic of pseudocysts in acute pancreatitis?
The finding of a pancreatic cystic lesion in a patient with a history of acute pancreatitis with or without amylase elevation should raise suspicion for a pseudocyst. The fluid of the cyst, if aspirated, is usually dark in color and contains pancreatic enzymes and bicarbonates.
What is the differential diagnosis of pancreatic cystically dilated side branches?
The differential diagnosis of cystically dilated side branches includes serous cystadenoma or mucinous cystic neoplasm [15]. Sometimes IPMN can be confused with chronic pancreatitis, but the normal appearing pancreatic parenchyma and the presence of mucus are in favor of IPMN.
What is the prevalence of mucinous cysts in pancreatic cysts?
Moreover, small incidental cysts in asymptomatic patients correspond to small branch-duct IPMN. Crippa et alreported that mucinous cystic neoplasms represent 25% of all pancreatic cystic neoplasms and IPMNs 50% of them [9].
