comment:A cyst present in only one islet in a section of pancreas is distinguished from angiectasis based on its large size, lack of an endothelial lining, and the absence of dilation of other vascular spaces ( Figure 1 and Figure 2 ).
recommendation:Islet cysts are uncommon but should be documented when present. A severity grade is not required.
