Intraductal Papillary Mucinous Tumors of the Pancreas

179 he term “intraductal papillary mucinous tumor of the pancreas” has been introduced as a unifying label for mucin-producing pancreatic neoplasms previously referred to as papillary and villous adenomas, mucinous duct ectasia, and mucin-producing adenomas and carcinomas with or without invasion. Unique clinical, radiologic, and pathologic characteristics of intraductal papillary mucinous tumors of the pancreas have been described [1]. Radiologic examination is necessary for treatment planning because imaging features may indicate the site of tumor origin in the pancreas in addition to extent of spread.
