Cystic pancreatic lesions are increasingly detected because of the improvement of CT and MR diagnostic techniques.
Pancreatic cystic lesions comprise a variety of categories including benign inflammatory and non-inflammatory conditions (pseudocyst or neoplasm such as serous cystadenoma -SCN-),
premalignant like mucinous cystic neoplasia (MCN) and papillary intraductal mucinous neoplasia (IPMN) and malignant,
as in the case of cystadenocarcinoma with cystic degeneration.
According to recent studies,
in the case of CT,
a precision of 70-80% can be achieved in the differentiation of benign lesions,
while a MR study has an accuracy of 85-91% to determine a diagnosis of malignancy. Further,
recent techniques like image acquisition after secretin stimulation obtain the highest sensitivity values.
there will be a small percentage of lesions whose diagnoses will remain indeterminate,
being necessary other methods such as intracystic fluid analysis or serological tumor markers.
