Abstract

Objective To investigate CT and MRI features of solid pseudopapillary tumor of the pancreas in the elderly group. Methods Imaging findings in 9 elderly patients of solid pseudopapillary tumor of the pancreas confirmed by pathology and misdiagnosed by radiologic imaging (including CT and MRI). Results Group CT: A total of 5 cases. 2 cases were large (the longest diameter>10cm), internal structure was uneven (cystic necrosis, hemorrhage and calcification could be observed. 3 cases were small (the longest diameter less than 5cm), the internal structure was uniform. 5 cases of lesions showed less clear boundaries. After enhancing lesions compared with normal pancreatic tissue: (1) A low degree of enhancement. (2) Peak enhancement appeared later. Group MRI: A total of 4 cases. Showed a cystic lesion signal change, 3 cases of intracapsular lesions have separated, 1 case of cystic lesions more uniform composition. After enhancing solid components lesions progressive enhancement. Conclusion Preoperative diagnosis of solid pseudopapillary tumor of the pancreas in the elderly group could be marked by radiologic imaging.
