Sonographic findings of solid and papillary epithelial neoplasm of the pancreas.

To evaluate the sonographic findings of solid and papillary epithelial neoplasm of the pancreas, a rare tumor occurring in young women. The sonographic findings of 11 cases of pathologically proven solid and papillary epithelial neoplasm of the pancreas were retrospectively evaluated. 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%). 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.
