Zhong L, et al. - By analyzing the imaging characteristics seen on endoscopic ultrasound, researchers provided criteria for the differential diagnosis of serous cystic neoplasms (SCNs) and mucinous cystic neoplasms (MCNs) in this prospective study involving 69 patients. All patients were verified by surgical pathology to have MCNs (31 patients) or SCNs (38 patients). Findings suggested that pancreatic cystadenomas that fulfil any two of the four imaging characteristics of head/neck location (lobulated shape, thin wall [0–2 mm] and > 2 septa) could be diagnosed as SCNs, and those that satisfy any 3 of the 4 imaging characteristics of body/tail location (round shape, thick wall [> 2 mm] and 0–2 septa) could be considered as MCNs.
