Solid pseudopapillary tumor of the pancreas mimicking pancreatic pseudocyst

Abstract

Solid pseudopapillary tumor of the pancreas is a low-grade malignancy, which is very rare and predominantly occurs in young women. We report a case of this tumor in a 30 year-old woman who was initially misdiagnosed with pancreatic pseudocyst based on CT scan findings. EUS with FNA revealed the diagnosis of solid pseudopapillary tumor and guided the surgical approach. This case emphasizes the importance of tissue diagnosis in patients with cystic lesions of the pancreas on CT scan and no obvious history of pancreatitis.
