CT Signs and Misdiagnosis Analysis of Solid Pseudopapillary Tumor of the Pancreas

Objective To explore the CT signs and causes of misdiagnosis of solid-pseudopapillary tumor of pancreas(SPTP).Methods The clinical data of 39 cases of SPTP confirmed by postoperative pathological examination were retrospectively analyzed.Results A total of 21 cases were misdiagnosed by CT examination in this group,and the misdiagnosis rate was 53.8%.Of the 39 cases,there were 23 cases with no clear history,5 cases with a history of pancreatitis,5 cases of elder patients with a history of"stomach disease",3 cases with a history of alcohol abuse,and 3 cases with a history of pancreatic trauma.Of them,11 cases were misdiagnosed as pancreatic pseudocysts,5 cases as pancreatic cancer,and 2 cases as pancreatic cystadenoma by CT examination;3 cases were unclearly diagnosed.The duration of misdiagnosis was 3-7 days.All 39 cases underwent surgical treatment,and all were confirmed as SPTP by postoperative pathological examination.Twenty-six cases were followed up for 1.5 to 8.0 years,and there was no tumor recurrence or other metastasis;7 cases were re-examined at the local county-level hospital,and the condition was unknown;6 cases were lost to follow-up.Conclusion SPTP is more common in young women.The minimal expansion of the pancreatic duct and bile duct is the most specific manifestation during CT examination.However,the diagnosis requires surgical pathology.Nonspecific clinical and CT manifestations of some patients,the doctors'insufficient understanding of their CT manifestations,failure to conduct differential diagnosis seriously,and poor CT examination techniques in the early years are the main reasons for the CT misdiagnosis of SPTP.
