Appraisal of needle-based confocal laser endomicroscopy in the diagnosis of pancreatic cysts

Figure 1 Different types of pancreatic cysts. A: Intraductal papillary mucinous neoplasm. A single papilla is visualized with a central fibrovascular core and overlying epithelium; B: Serous cystadenoma: Branching and tortuous network of multiple blood vessels in a “fern like” pattern. This is has been termed as “superficial vascular network”[22]; C: Pseudocyst: Clusters of bright, floating particles with a background which is nondescript and lacks blood vessels; D: Mucinous cystic neoplasm: Solitary epithelial bands without formation of papillae.
