Intraductal Papillary-Mucinous Tumors of the Pancreas: Differential Diagnosis Between Benign and Malignant Tumors by Endoscopic Ultrasonography

Abstract

Main duct type tumors with > or =10 mm dilated MPD, branch duct type tumors (>40 mm) with irregular septa, and large mural nodules (>10 mm) strongly suggest malignancy on EUS. EUS would be a useful modality for differentiating between benign and malignant IPMT.
