“…It is important to look for this characteristic because it is highly specific to pseudocysts. Macari et al [55] reported that on MRI, 13 of 14 (93%) pseudocysts had debris but only 1 (4%) of 22 cystic neoplasms had debris. Debris is very easily seen with EUS.…”

Cystic lesions of the pancreas are being diagnosed with increasing frequency, covering a vast spectrum from benign to malignant and invasive lesions. Numerous investigations can be done to discriminate between benign and non-evolutive lesions from those that require surgery. At the moment, there is no single test that will allow a correct diagnosis in all cases. Endoscopic ultrasound (EUS) morphology, cyst fluid analysis and cytohistology with EUS-guided fine needle aspiration can aid in this difficult diagnosis.

“…Large pancreatic pseudocysts can cause local mass effect. (9) They can also be complicated by secondary infection, bleeding and rupture; secondary infection is associated with a high rate of morbidity and mortality, and thus requires emergent drainage.…”

A 16-year-old Chinese male patient, who had a past medical history of hyperventilation complicated by carpopedal spasms, presented to the emergency department with constipation of five days' duration, colicky abdominal pain, lethargy, weakness and body aches. He was still able to pass flatus, and did not complain of vomiting, fever, chills or rigors. On examination, the abdomen was soft and non-tender. Digital rectal examination was unremarkable, as was the full blood count, except for a raised total white blood cell count of 16.6 × 10 9 /L. Renal and liver function tests and urinalysis were also unremarkable. The patient was hospitalised for further investigation of constipation. During his hospital stay, abdominal radiography was performed (Fig. 1). He subsequently desaturated acutely, and computed tomography (CT) was performed (Fig. 2)

“…In cases where the morphological features of cystic lesions are not sufficient for arriving at a conclusive diagnosis, further characteristics have to be evaluated such as evidence of a solid component, infiltrating tumor growth exceeding the organ borders or pancreatic ductal obstruction. Debris in combination with a history of pancreatitis is indicative of pseudocysts [14,15]. …”

The early and accurate characterization of pancreatic masses remains a challenge in diagnostic radiology, while the continuously evolving diagnostic possibilities give rise to an ever-increasing number of incidentally found pancreatic masses. This article discusses the relevance and role of ultrasound, endoscopic ultrasound, computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) in the diagnosis of pancreatic lesions. Specific protocols such as MR cholangiopancreatography and multiphase CT allow for a close characterization. While CT and MRI deliver information to further evaluate pancreatic disease, PET/CT has shown potential for staging purposes and in the clinical follow-up of pancreatic cancer patients. Common differential diagnoses regarding pancreatic cancer are discussed, and typical imaging features of anatomical variations, cystic lesions and pancreatitis are illustrated, together with clinical signs of pancreatic disease. The use of cross-sectional imaging in correlation with clinical features allows for an accurate and early detection of pancreatic masses and assists in differentiating benign from malignant disease.
