Pancreatic pseudocyst

Pancreatic Pseudocyst

Pancreatic pseudocyst (pronunciation: pan-kree-at-ik soo-doh-sist) is a fluid-filled sac that forms in the pancreas. It is a complication that can occur after pancreatitis, which is inflammation of the pancreas.

Etymology

The term "pancreatic pseudocyst" is derived from the Greek words "pankreas" (all flesh), "pseudo" (false), and "kystis" (bladder). It refers to a false cyst that forms in the pancreas.

Definition

A pancreatic pseudocyst is a collection of fluid, often rich in pancreatic enzymes, surrounded by a wall of fibrous tissue. Unlike true cysts, pseudocysts do not have a specialized lining of epithelial cells. They are usually a result of acute pancreatitis, but can also occur with chronic pancreatitis or pancreatic trauma.

Symptoms

Symptoms of a pancreatic pseudocyst can include abdominal pain, nausea, vomiting, weight loss, and a palpable mass in the abdomen. In some cases, the pseudocyst can become infected, leading to fever and increased pain.

Diagnosis

Diagnosis of a pancreatic pseudocyst is typically made through imaging studies such as computed tomography (CT) scans, magnetic resonance imaging (MRI), or endoscopic ultrasound (EUS).

Treatment

Treatment options for a pancreatic pseudocyst depend on the size and symptoms of the pseudocyst. Small, asymptomatic pseudocysts may be monitored without intervention. Larger or symptomatic pseudocysts may require drainage, which can be performed endoscopically, percutaneously, or surgically.
