Figure 1. Endoscopic ultrasound imaging of (A) A microcystic lesion (circle) in the tail of the pancreas consistent with serous cystadenoma (SCA). (B) A large uniocular thin-walled cyst (arrows) measuring 33 mm × 27 mm in the body of pancreas. The cyst is uniformly anechoic with no solid component. The cyst has no evident communication with the pancreatic duct on the static image and therefore is consistent with the definition of a mucinous cystic neoplasm (MCN). (C) Multiseptated (arrow) thin-walled cyst in the head and neck of the pancreas. The cyst communicates with the non-dilated pancreatic duct, but this is not evident on the static image, consistent with the definition of a branch-duct IPMN. (D) Another cluster of grape-like cysts (small multiseptated cysts) communicating with a dilated PD (arrow), consistent with mixed main-duct and branch-duct IPMNs. Patient is on images surveillance.
