Solid and papillary epithelial neoplasm of the pancreas: radiographic, CT, sonographic, and angiographic features
Solid and papillary epithelial neoplasm of the pancreas is a nonfunctioning tumor seen as a slowly enlarging upper abdominal mass in young women. It is usually large, well encapsulated, and undergoing necrotic degeneration. On ultrasound, it is sharply defined, nonhomogeneous, and lacking central enhancement. On angiography, it can be avascular or hypovascular depending on the degree of necrosis. Calcification has not been reported, and metastatic deposits are rare. Excision leads to an excellent prognosis.
