The incidence of these cystic lesions increases with age. One autopsy study has demonstrated that up to a quarter of elderly individuals harbor cystic lesions of the pancreas at their demise.1 With the ever increasing use of computed tomography (CT) and magnetic resonance imaging (MRI), cystic lesions of the pancreas are being defined with progressively greater frequency, and an ever increasing number are asymptomatic at discovery.2,3 Some of these lesions will be malignant or have malignant potential at diagnosis, while others are clearly benign and may not warrant further surveillance. Resection of benign cystic pancreas lesions or those containing only carcinoma in situ leads to nearly universal survival, while surgery for invasive carcinoma associated with cystic neoplasms generally has a more favorable prognosis than the results for pancreatic ductal adenocarcinoma.4,5 Thus careful consideration must be given to the diagnosis and prognostic implications of these lesions.
