Pseudocyst is a swelling that develops on the pancreas and is often due to leakage of pancreatic secretion outside of the pancreas. Formation of scar tissue around the leakage causes a swelling called a pseudocyst. Patients with pseudocyst often present with abdominal pain that is aggravated by meals. In some patients, a pseudocyst develops without any symptoms.
Surgery is usually needed when the pseudocyst is causing symptoms. However, not all cysts require treatment. In many cases, the pseudocysts may improve and go away on their own. In a patient with a small (less than 6 centimeters) cyst that is not causing any symptoms, careful observation of the cyst with periodic CT scans is recommended.
