Radiologic Findings of Pancreatic Cystic Neoplasms / 대한내과학회지

ABSTRACT

With the widespread use of radiologic modalities such as ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI), cystic neoplasms of the pancreas are being increasingly detected; however, developing an accurate characterization and making a differential diagnosis are difficult because of their overlapping morphologic characteristics. Serous cyst adenoma is a common benign neoplasm that is typically observed as a multi-cystic mass or lobulated cyst with or without internal septation. In comparison, mucinous cystic neoplasms appear as smooth cystic tumors with or without internal septation. Finally, intraductal papillary mucinous neoplasms of the pancreas are pleomorphic cystic lesions or clubbed fingerlike tubular structures. These typical imaging findings can help clinicians differentiate cystic neoplasms of the pancreas.
