Abstract

Solid serous cystadenoma of the pancreas is the rarest subtype of serous cystadenoma. Cystic structures are difficult to recognize by imaging studies. In the clinical setting, it is crucial to discriminate a solid serious cystadenoma from other solid pancreatic tumors. The present study reported a case of solid serous cystadenoma in which the magnetic resonance cholangiopancreatography (MRCP) findings were useful for diagnosis and decision-making regarding the surgical strategy, with a review of the previous reports of solid serous cystadenoma. A 50-year-old woman was referred to our hospital for investigation of a pancreatic body mass. A 2-cm hypervascular solid tumor was revealed by computed tomography. No typical radiological imaging findings of small cysts were detected, such as a honeycomb structure, and an adequate specimen could not be gained by biopsy under endoscopic ultrasonography. However, the tumor showed high intensity on MRCP, suggesting its cystic nature. A solid serous cystadenoma was suspected based on these radiological findings, and middle segment pancreatectomy was performed as a function-preserving surgery. The histological findings were compatible with a solid serous cystadenoma. In conclusion, MRCP imaging may be helpful for diagnosis and decision-making regarding the most appropriate surgical method for solid serous cystadenomas.
