1.2 % of patients have a pancreatic cyst at CT or MRI and >50% are neoplastic Pancreatic cysts in ~25% of autopsies: – Atypia in 16% of these & carcinoma-in-situ in 3% Some pancreatic cancers are now thought to be derived from these cysts Spinelli et al.

Undefined small pancreatic cysts are, however, frequent and often have no effect on a patient’s survival in the absence of any risk factor for malignancy. 33 On that basis, the European Study Group on Cystic Tumours of the Pancreas recommends that, in the absence of risk factors for malignancy, undefined cysts <15 mm in size should be re-examined every year—if they are stable for 3 years

The MRI shows a pancreatic fluid collection with dependent internal debris typical of walled off necrosis in necrotizing pancreatitis (7). MRI shows a lesion, which consists of multiple small cysts. Retroperitoneal lesions (extrinsic to the pancreas) can mimic pancreatic cystic lesions, when close to the gland. Examples include: cystic lymphadenopathy (e.g. necrotic) duodenal diverticulum; Practical points.

Radiology department of the Academical Medical Centre, Amsterdam and the Alrijne hospital in Leiderdorp, the Netherlands Cystic pancreatic lesions are increasingly identified due to the widespread use of CT and MRI.

This type of imaging is especially helpful for evaluating cysts in the pancreatic duct. American College of Radiology baseline size category of 15–25-mm pancreatic cystic neoplasms (PCNs) demonstrated the highest (3.1 times) likelihood of growth, as compared with the category of PCNs smaller than 5 mm.

Neoplastic cystic lesions, which are the most important, owing to their profound impact on patient prognosis and the frequent necessity of surgical treatment, are described in detail in this chapter. Many patients in whom a pancreatic head tumor is detected by ultrasound still undergo ERCP. Although ERCP has a high sensitivity for detecting pancreatic head tumors, it is nowadays no longer indicated because the diagnosis can usually be made with non-invasive tests.
