Radiologic features of cystic, endocrine and other pancreatic neoplasms.
This article presents imaging features of cystic, endocrine and other pancreatic 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 appearence 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 ductectatic mucinous cystic neolasm. Endocrine tumors of pancreas are hypervascular and can be depicted on early dynamic enhanced crosssectional imaging modalities or on angiography when they are <1 cm. Pancreatic metastases and lymphomas are rare neoplasms which should also be included in differential diagnosis for pancreatic masses.
