Radiologic features of cystic, endocrine and other pancreatic neoplasms

This article presents imaging features of cystic, endocrine and other pancr eatic neoplasms. Microcystic adenoma which is composed of small cysts (< 2 cm), its macrocystic subgroup contains solitary cyst. Multiple cysts larger than 2 cm are associated with mucinous cystic neoplasm. Swiss cheese appea rence with central calcification is characteristic for microcystic adenomas . Septal and mural enhancement as well as larger size (>2 cm) are accounted for mucinous cystic neoplasms, its variant along pancreatic duct is ductec tatic mucinous cystic neolasm. Endocrine tumors of pancreas are hypervascul ar and can be depicted on early dynamic enhanced crosssectional imaging mod alities or on angiography when they are <1 cm. Pancreatic metastases and ly mphomas are rare neoplasms which should also be included in differential di agnosis for pancreatic masses. (C) 2001 Elsevier Science Ireland Led. All r ights reserved.
