A 59-year-old woman was admitted to our hospital because of suspicion of a tumor of the pancreatic body based on the abdominal ultrasound findings during a periodic medical checkup. Blood biochemical, tumor marker, and pancreatic endocrine hormone testing yielded no abnormal findings. The tumor was strongly enhanced by abdominal contrast-enhanced CT and angiography, and differentiated from a pancreatic non-functioning endocrine tumor. MRI showed that the tumor contained a large serous portion, and pancreatic serous cystadenoma was suspected. Distal pancreatectomy was performed. Sectioning of the tumor revealed a solid structure and no cysts. The histopathological diagnosis was serous cystadenoma. We report a case of pancreatic serous cystadenoma that appeared to be a solid tumor based on the diagnostic imaging and macroscopic findings.
