CONCLUSION: The existence of excrescent nodules in the cystic component of intraductal papillary neoplasms (IPN) on computed tomography (CT) is useful for differentiating between malignant and benign lesions. BACKGROUND: We sought to evaluate the ability of CT to differentiate malignant from benign lesions in IPN of the pancreas. METHODS: CT findings in 20 cases of IPN (11 benign and 9 malignant lesions) were compared with histopathological findings from subsequent surgery. RESULTS: The size of the cystic portion on CT did not correlate with the malignant potential of the lesion. Seven (78%) of 9 malignant lesions had excrescent nodules on CT, whereas 1 (9%) of 11 benign lesions did.
