- Figure 1
Gross appearance of a mucinous cystic lesion of the pancreas.
- Figure 2
Endoscopic ultrasound of a malignant mucinous lesion with a mass filling the cystic space. The outer wall of the cyst is indicated by the white arrow.
- Figure 3
Contrast-enhanced CT scan showing mucinous cystadenoma. A large cystic tumor with small cysts clustered at its periphery (arrow). (Adapted with permission from: Kim YH et al).68
- Figure 4
Contrast-enhanced CT scan showing branch duct IPMN. A cystic lesion can be seen with a markedly dilated side branch duct with wall thickening (arrow). (Adapted with permission from: Kim YH et al.)68 IPMN, intraductal papillary mucinous neoplasm.
- Figure 5
MR cholangiopancreatogram showing a lesion suspicious for IPMN. Image shows a cystic, grape-like pancreatic lesion. It is not clear whether there is a communication of the mass and the pancreatic duct. Endoscopic retrograde cholangiopancreatography (ERCP) would be useful in this situation. (Adapted with permission from: Kim YH, et al.)68 IPMN, intraductal papillary mucinous neoplasm.
- Figure 6
Cytology slide of IPMN aspirate from EUS-FNA. An intact cluster of moderately atypical epithelial cells with a single residual mucin vacuole. Even small numbers of such atypical cells warrant a suspicion of carcinoma. EUS, endoscopic ultrasound; FNA, fine needle aspiration; IPMN, intraductal papillary mucinous neoplasm.
- Figure 7
EUS view of the EUS-RFA probe. EUS, endoscopic ultrasound; RFA, radiofrequency ablation.
- Figure 8
Schematic with a brief summary of management of cystic pancreatic lesions. CEA, carcinoembryonic antigen; EUS, endoscopic ultrasound; FNA, fine needle aspiration; MRCP, MR cholangiopancreatography.

Pseudocyst MCN IPMN Location Anywhere Primarily body and tail Head, body and tail EUS features Primarily unilocular, anechoic or contains debris Unilocular or oligolocular Multiple cysts communicating with pancreatic duct, dilated pancreatic duct Cystic fluid analysis CEA Low High High Amylase High Usually low but may be high High Cytology Inflammatory cells Extracellular mucin, mucinous epithelial cells and atypical cells may be seen Extracellular mucin, mucinous epithelial cells and atypical cells may be seen CEA, carcinoembryonic antigen; EUS, endoscopic ultrasound; IPMN, intraductal papillary mucinous neoplasm; MCN, mucinous cystic neoplasm.
