title: Sonographic findings of solid and papillary epithelial neoplasm of the pancreas.
abstract: OBJECTIVE
  To evaluate the sonographic findings of solid and papillary epithelial neoplasm of the pancreas, a rare tumor occurring in young women.
  
  
  METHODS
  The sonographic findings of 11 cases of pathologically proven solid and papillary epithelial neoplasm of the pancreas were retrospectively evaluated.
  
  
  RESULTS
  In 6 cases (55%), combined cystic and solid portions of the masses were observed, whereas only solid-looking masses without anechoic cystic portions were seen in 4 cases (36%). One case (9%) had marginal calcification, consequently, the internal architecture was not evaluated by sonography. Internal echoes were seen in 3 of 6 cystic and solid masses. Septa were seen in 3 cases. Among 11 cases of solid and papillary epithelial neoplasm, tumor margins were well defined in 10, and tumor capsules were detected in 9 (echogenic in 7 and hypoechoic in 2). Calcifications were seen in 3 cases (27%).
  
  
  CONCLUSIONS
  The characteristic sonographic findings of solid and papillary epithelial neoplasm were well-encapsulated, cystic, and solid masses, but sometimes the mass was seen as a pure solid-looking mass or had internal septations or calcifications.
